Six-ten on a Wednesday morning.

Phum walked into Benjakitti Park at the same pace as always, the same sneakers, the same black coffee in the same paper cup from the stand by the road. For three mornings now he'd looked for the olive-green yoga mat under the banyan tree by the lake, and for three mornings it hadn't been there.

It wasn't as if Baitoey had ever made an appointment with him. She never had, and he'd never asked. It was just something that happened — two people arriving in the same place around the same time, sometimes talking, sometimes just sitting in silence on opposite ends of a mat. But for three days now there was only grass, mowed too neatly by someone, no flattened patch where a mat had been, no familiar water bottle.

He walked his usual loop around the lake without thinking much of it, and only noticed, back at the gate, that he'd been walking slower than usual without meaning to. As if some part of him had been waiting.

At the office, ten past nine, Baitoey had arrived before him as always, sitting at her desk, headphones around her neck, Figma open on her screen.

"Morning," Phum said as he passed.

"Morning," she answered, without looking up.

That was all.

Usually there was more — she'd ask if he'd slept enough, tease him about the demo, or just flash a quick smile before going back to work. Today nothing followed the word "morning" at all.

Phum sat down at his own desk, opened his laptop, and tried not to think too much about it.

Pae wandered over and leaned against the edge of the desk, a can of coffee in hand. "Hey. Notice anything?"

"What?"

"Baitoey. She's been quiet for like three, four days."

"Probably tired from the demo," Phum said, not looking at him.

"Maybe," Pae said, sounding like he didn't quite believe it himself, then walked back to his desk.

Phum stared at his screen and typed nothing.

He thought about Monday night, after the demo had gone well, when Baitoey had said, "Take tomorrow off, okay," in a tone that sounded more like she was talking to herself than to him. At the time he'd assumed she was just exhausted. He'd assumed one day off would fix it.

But it had been more than four days now.

—

Thursday afternoon, Phum sent her a work message about a component she'd designed — a real question, not an excuse to talk.

"Can I just use the spacing from the second frame, or do you need to revise it first?"

The answer came fast. Within two minutes.

"You can use the second frame. No need to wait."

That was it. No emoji, no "thanks for asking," none of the little flourishes she usually left at the end of a message. Just the most efficient answer possible.

Phum read it twice before putting his phone down.

It occurred to him that he was doing something he'd never done before — rereading a work message to search for a tone that wasn't actually there.

That evening, once most people had drifted home, he walked over to her desk. Only the two of them left, the way it had been the first time he'd asked her to lunch.

"Heading out?" he asked, trying to keep his voice as ordinary as possible.

"Yeah, I have plans," Baitoey said, packing her laptop into her cloth bag. She didn't say what kind of plans.

"Okay. Drive safe."

"Thanks."

She walked off. Her sandals clicked against the tile in a steady rhythm, then went quiet at the elevator doors.

Phum stood there a moment longer, looking at the empty space on the desk she'd just left. He noticed there was no iced latte cup sitting there the way there usually was all day — just the same plain water bottle.

She had plans. He didn't ask what. Not because he didn't want to know, but because he felt he no longer had the right to ask.

—

That night in his apartment, Phum sat staring at his habit-tracking app. His streak read fifty-one. A long row of green squares stretching far enough that he had to scroll to see the start of it.

He should have felt good.

Instead, a question surfaced that he'd never let himself ask directly before — if Baitoey weren't there, weren't watching, weren't aware, didn't care at all, would he still be waking up at six tomorrow?

The answer he wanted to give was an immediate yes. But something more honest in him made him sit with the question longer than he would have liked.

He thought back to the early days of exercising — every time he did five squats beside the coffee machine, there had always been an image of Baitoey hovering somewhere in his head. The image of her walking past and noticing. The image of her thinking he'd changed. It had been a motivation that worked so well he'd never paused to ask what kind of motivation it actually was.

But she wasn't watching him anymore. She'd gone quiet like a switch had been flipped somewhere. And he was still waking up at six. Still not touching the instant noodles that weren't in his cupboard anyway. Still logging his streak every night before bed, exactly as before.

Maybe that was the answer — not that he didn't care whether she was watching, but that these habits had quietly become part of him, separated from the original reason he'd started them, without his even noticing the moment it happened.

Or maybe he just wanted to believe that, because it sounded better than the truth — that he still wasn't sure.

—

Friday was the fifth day of the silence.

Phum worked until nine in the evening. Pae and Puangthong had left by six. P'Neung was out at a client meeting. The office was down to one light over his own desk and one over Baitoey's, where she still sat working quietly on something.

He decided to close his laptop, pack his bag, and walk past her desk toward the elevator.

"Heading out," he said, trying to make it sound as casual as possible.

Baitoey looked up. The first time in days he felt she was actually looking at him, not just letting her eyes pass over him.

She was quiet for a few seconds, as if choosing her words.

"Phum," she said finally. "Thank you."

He stopped walking. "Thank you for what?"

"Just—" she gave a small smile that didn't quite reach her eyes. "Nothing. Never mind. Get home safe, okay?"

She turned back to her screen before he could ask anything else.

Phum stood there a few more seconds, waiting to see if anything else would follow. Nothing did. She went back to her work as if the sentence she'd just said had never existed.

He walked to the elevator and pressed the button down, watching his own reflection in the stainless doors that hadn't opened yet.

Thank you for what — the question circled in his head the whole way down. Thank you for asking about work directly, without dancing around it. Thank you for not pressing her about what was wrong. Thank you for letting her stay quiet without having to explain. Or thank you for something he hadn't even thought of yet.

The elevator opened. He stepped in alone, watching the floor numbers count down.

The same sneakers he'd worn to work that day still had a smear of dirt from the park that morning stuck to the sole.

Tomorrow morning he would go back to the park again, whether or not that olive-green mat was waiting under the banyan tree.

He just didn't know, right now, what he was really doing it for — for himself, the way he wanted to believe, or in the hope of someone who might never come back to sit there again.

His phone buzzed once in his pocket. He pulled it out.

A message from his mother, sent at six that evening, which he hadn't opened yet.

"Have you eaten dinner yet, son?"

He smiled faintly and typed a reply the moment the elevator doors opened onto the lobby.

"Not yet, Mom. I'll cook something when I get home."

He sent it and walked out of the building into the early dark settling over Bangkok, with no idea that the next message from his family wouldn't come from his mother at all — but from his sister, Dia, and that it would change everything he thought he already knew about himself.

周三早上六点十分。

阿普像往常一样走进本杰吉提公园，同一双运动鞋，路边摊买的同一杯黑咖啡。已经三个早晨了，他在湖边那棵菩提树下寻找那块橄榄绿色的瑜伽垫，却始终没有找到。

并不是拜黛跟他约好了每天早上见面——她从没约过，他也从没问过。这只是一件自然发生的事：两个人在差不多的时间出现在同一个地方，有时聊几句，有时只是各自坐在垫子的两端不说话。但这三天，那个地方只剩下被人修剪得过分整齐的草地，没有垫子压过的痕迹，没有那个熟悉的水瓶。

他照常绕湖走了一圈，没怎么多想，直到走回大门时才发现自己不知不觉走得比平时慢——好像在等什么人。

办公室里，九点十分，拜黛已经像往常一样先到了，坐在自己桌前，耳机挂在脖子上，电脑屏幕上开着Figma。

"早。"阿普走过时说。

"早。"她回答，眼睛没有离开屏幕。

仅此而已。

平时这之后总会有点别的——她可能会问他昨晚睡够了没，或者拿demo开玩笑，或者只是匆匆一笑再回去工作。今天，"早"这个字之后什么都没有。

阿普坐回自己的位置，打开笔记本电脑，努力不去多想。

帕走过来，靠在桌边，手里拿着一罐咖啡。"嘿，你注意到什么了吗？"

"什么？"

"拜黛啊。安静了三四天了。"

"可能是demo做累了吧。"阿普说，眼睛没看他。

"也许吧。"帕的语气听起来连自己都不太信，然后走回了自己的位置。

阿普盯着屏幕，什么都没打。

他想起周一晚上demo通过之后，拜黛说"明天休息一天吧"时的语气——听起来更像是在对自己说，而不是对他说。当时他以为她只是累了，以为休息一天就好了。

可现在已经过去四天多了。

——

周四下午，阿普在工作群里问了一个关于拜黛设计的组件的问题——是真正要确认的事，不是找借口说话。

"第二个画框里的间距可以直接用吗，还是要等你修改？"

回复来得很快，两分钟之内。

"直接用第二个就行，不用等。"

到此为止。没有表情符号，没有她平时常加在后面的那句"谢谢问我哦"或者什么玩笑话，只有一个尽可能精准、不带任何多余东西的答案。

阿普把那条消息看了两遍才放下手机。

他突然意识到自己在做一件以前从没做过的事——反复读一条工作消息，去找一种其实根本不存在的语气。

那天晚上，大部分人都陆陆续续走了，他走到拜黛的桌边。办公室里只剩他们两个人，跟第一次约她吃午饭那天很像。

"要走了吗？"他问，尽量让语气听起来很平常。

"嗯，有约。"拜黛说，把笔记本电脑收进布包，没说是什么约。

"好，路上小心。"

"嗯，谢谢。"

她走了出去。凉鞋踩在地砖上发出规律的声音，然后在电梯门口消失。

阿普在原地站了一会儿，看着她刚刚离开的那张空桌子。他注意到今天桌上没有她平时整天放在那里的冰拿铁，只有那个一直用的白水瓶。

她说有约，阿普没有再问。不是因为不想知道，而是觉得自己已经没有资格问了。

——

那天晚上，阿普坐在房间里盯着手机上的习惯追踪软件。连续打卡的天数显示五十一天，绿色的方块连成一长串，长得要滑动屏幕才能看到开头。

他应该感到高兴的。

可浮现在脑子里的，却是一个他从未真正问过自己的问题——如果拜黛根本不在那里，不会看到，不会知道，也不会在意，他明天早上还会六点起床吗？

他想给的答案是"当然会"。但更诚实的那部分自己，让他坐在那里想了比预想中更久。

他想起刚开始锻炼的那些日子——每次在咖啡机旁做五个深蹲时，脑子里总会浮现拜黛的影子。她可能正好走过，看到的画面。她可能会觉得他变了的画面。那是一种运作得非常好的动力，好到他从没停下来想过，那到底是哪一种动力。

但现在她不再看他了。她像被人按下了某个开关，突然安静下来。而他依旧六点起床，依旧没碰那本来就不在柜子里的泡面，依旧每晚睡前在软件里记录打卡，跟以前一模一样。

或许这就是答案——不是他不在乎她有没有在看，而是这些习惯不知不觉间已经变成了他自己的一部分，早就跟最初开始的理由分开了，只是他自己没察觉到是什么时候发生的。

又或者，他只是想这样相信，因为这个说法听起来，比"他其实也还不确定"要好听得多。

——

周五，是沉默的第五天。

阿普一直工作到晚上九点。帕和彭东六点就走了，珀一哥外出见客户。办公室里只剩下他桌上那一盏灯，还有拜黛桌上那一盏——她还在那儿，安静地做着什么。

他决定关上电脑，收拾好包，走过她的桌子往电梯方向去。

"我先走了。"他说，尽量让语气显得轻松。

拜黛抬起头来。这是这几天里，他第一次真正感觉到她在看着他，而不是视线只是从他身上滑过去。

她沉默了两三秒，像是在挑选用词。

"阿普。"她终于开口，"谢谢你。"

他停下脚步。"谢什么？"

"就……"她笑了一下，那笑容没有到达眼睛，"没什么。没事。路上小心。"

她在他还能再问之前，就转回了电脑屏幕。

阿普又站了几秒，等着看是否还有后话。没有。她回到自己的工作里，仿佛刚才那句话从未存在过。

他走向电梯，按下向下的按钮，看着自己映在还未打开的不锈钢电梯门上的影子。

谢什么——这个问题在他下楼的整段路上一直转着。谢谢他直接问工作上的事，没有拐弯抹角。谢谢他没有继续追问她怎么了。谢谢他能让她安静下来，不必解释。或者，谢的是某件他还没想到的事。

电梯门开了，他一个人走进去，看着楼层数字一点点往下跳。

他今天穿来上班的那双运动鞋鞋底上，还沾着今天早上公园里带来的一点泥土。

明天早上他还是会去公园，无论那块橄榄绿色的垫子是否还会在菩提树下等着他。

只是现在，他还不知道自己究竟是为了什么——是像他想相信的那样，为了自己；还是为了等一个可能再也不会回到那里坐下的人。

口袋里的手机震了一下。他拿出来看。

是妈妈发来的消息，晚上六点发的，他到现在才看到。

"儿子，晚饭吃了没？"

他笑了一下，电梯门打开到大堂的那一刻，立刻回复。

"还没呢妈，回家自己弄点吃的。"

发出去之后，他走出大楼，融入曼谷刚刚降下的夜色里，完全不知道，下一条来自"家里"的消息，将不会来自妈妈——而是来自妹妹蒂尔，并且会改变他自以为已经了解的、关于自己的一切。
