他们是在高中认识的。
两个安静到近乎透明的人，坐在教室的角落里，像两棵被修剪过度的树，努力把自己缩进允许的形状里。那时候没有人管那叫抑郁症。老师叫它不合群，家长叫它不争气，同学叫它怪。
他们从来没有认真谈论过彼此的伤口。不需要。
他们会一起走到天台上去。不说话，就坐着，看城市在脚下铺展开。风从很远的地方吹过来。
有一天，他看见她被老师叫到办公室。隔着玻璃窗，他看见老师的手指伸进她的裙子里，看见她低着头，肩膀在微微发抖。他站在走廊里，攥紧了拳头。
她出来的时候，他就站在那里。没有说话。两个人并排走过走廊，穿过操场，走上天台。风很大，吹得校服猎猎作响。
后来有一次，他们又去了天台。那天下了很大的雨。雨点砸在水泥地面上，密密麻麻，像什么人在很远的地方敲打一扇关了很久的门。她掏出一支录音笔，按下录音键，对着雨幕举了很久。
下楼的时候，她把录音笔塞进他手里。
“送你的。”
他没问为什么。接过来，放进口袋里。
后来他们上了大学。她去了重庆，他去了昆明。两座被雨水浸泡的城市。她在嘉陵江边听雨，他在翠湖边听雨。他们偶尔联系，发一条消息，有时候只是一张雨天的照片。
再后来他们各自出了国。她去了伦敦，他来了温哥华。两座以阴雨闻名的城市。连绵的雨季像一条跨越太平洋的绳子，松松地系着什么。他常常在深夜拿出那支录音笔，听那段高中天台的雨声。十几年了，音质已经模糊，但雨还是那场雨。
有一天她发来一段很长的语音。
她说她去了尼泊尔，爬了安纳普尔纳。她说那座山在下雨的时候美得不像人间，云雾从山谷里涌上来，把整个世界吞进去，又慢慢吐出来。她说她在山顶录了一段雨声。觉得自己在那一刻特别平静，平静到几乎可以原谅所有的事情。
他坐在温哥华的公寓里，听完了那段语音。窗外也在下雨。他想回复什么，想了很久，最后只发了一个句号。她应该会懂的。
那是她最后一次联系他。
后来她搬去了悉尼。悉尼不怎么下雨。阳光炽烈，天空蓝得发白，像一座被冲洗干净的城市，不留任何痕迹。他听说她身边有了一个人，把她从陈旧的生活里变得崭新。他想，也许她终于走到了雨停的地方。也许她的世界里终于有了一种不需要录音笔就能记住的声音。
站在阳光里的那个人不是他。这件事他想了想，觉得没什么。又想了想，觉得也不完全是没什么。
然后有一天，他在新闻上看到了她的名字，自杀。
他盯着屏幕看了很久，久到屏幕自动暗下去。他没有哭。他只是觉得胸口有一个地方塌了下去。安静地，缓慢地，像一栋很久没人住的房子终于承认了自己是废墟。
悉尼的阳光那么好。有人那么用力地爱着她。她已经走了那么远。
但也许有些东西一旦在很早很早的时候碎掉了，就真的拼不回来。不管后来的人多努力，不管后来的城市多晴朗。那些碎片已经嵌进了骨头里，和她长在了一起。
他买了一张机票，飞到加德满都，背上登山包，走上了她曾经走过的那条路。
临近山顶的那天，暴雨倾盆而下。
雨水顺着他的脸往下淌。他分不清那是雨，是汗，还是别的什么。他想起天台上举着录音笔的她，嘉陵江边拍雨天照片的她，安纳普尔纳山顶说”我很平静”的她。以及最后走进悉尼阳光里，却再也没有走出来的她。
他站在山顶。站了很久很久。
雨没有停。云雾从山谷里涌上来，把他吞进去，又吐出来。和她描述的一模一样。但他知道，他们站在同一个位置，看见的是完全不同的东西。
他开始下山。
走之前，他把那支录音笔放在了山顶的一块石头上。
他走下山去。
雨还在下。
They met in high school.
Two people so quiet they were nearly transparent, tucked into the corners of the classroom like trees pruned too aggressively, trying to compress themselves into permissible shapes. Back then, nobody called it depression. Teachers called it antisocial. Parents called it a disappointment. Classmates just called it weird.
They never really talked about each other’s wounds. They didn’t need to.
They would walk up to the rooftop together. Say nothing, just sit, watching the city unfurl beneath their feet. The wind came from somewhere far away.
One day, he saw her get called into the teacher’s office. Through the glass window, he saw the teacher’s hand slip under her skirt. He saw her head bowed, her shoulders trembling faintly. He stood in the hallway, fists clenched.
When she came out, he was just standing there. Neither of them said a word. They walked side by side down the corridor, across the schoolyard, up to the rooftop. The wind was strong, whipping their uniforms into sharp snaps against the air.
Later, they went to the rooftop again. It was pouring that day. Raindrops hammered the concrete, dense and relentless, like someone far away was knocking on a door that had been shut for a very long time. She pulled out a voice recorder, pressed the button, and held it out toward the curtain of rain for a long while.
On the way downstairs, she pressed the recorder into his hand.
“For you.”
He didn’t ask why. He took it and slipped it into his pocket.
They went to different universities. She went to Chongqing. He went to Kunming. Two cities soaked in rain. She listened to the rain by the Jialing River; he listened by Green Lake. They kept in touch now and then — a message here, sometimes just a photo of a rainy day.
Later, they each left the country. She went to London. He came to Vancouver. Two cities famous for their grey, endless rain. The drawn-out rainy seasons were like a rope stretched across the Pacific, loosely tying something together. Late at night he would often take out that voice recorder and listen to the rain from the high school rooftop. Over a decade old now, the sound had gone fuzzy, but the rain was still the same rain.
One day, she sent him a long voice message.
She said she’d been to Nepal, hiked Annapurna. She said the mountain in the rain was beautiful beyond this world — clouds surging up from the valley, swallowing everything whole, then slowly releasing it again. She said she’d recorded the sound of rain at the summit. Said she felt, in that moment, a profound stillness — so still she could almost forgive everything.
He sat in his Vancouver apartment and listened to the entire message. Outside his window, it was raining too. He wanted to say something back, thought about it for a long time, and in the end sent only a period. She would understand.
That was the last time she ever reached out.
He heard she’d moved to Sydney. Sydney doesn’t get much rain. The sunlight there is fierce, the sky bleached white-blue, like a city scrubbed clean of all traces. He heard she had someone new, someone who lifted her out of her weathered old life and made it bright again. He thought: maybe she’d finally walked to a place where the rain had stopped. Maybe her world finally had a sound worth remembering without a recorder.
The person standing in the sunlight was not him. He thought about this, and decided it was fine. Then he thought about it some more, and decided it wasn’t entirely fine.
Then one day, he saw her name in the news. Suicide.
He stared at the screen for a long time, so long that it dimmed itself to black. He didn’t cry. He just felt something in his chest cave in. Quietly. Slowly. Like a house no one had lived in for years finally admitting it was a ruin.
The sunlight in Sydney was so good. Someone loved her so fiercely. She had already come so far.
But maybe some things, once shattered early enough, can never truly be pieced back together. No matter how hard the people who came after tried, no matter how clear the skies of the cities that followed. The fragments had already embedded themselves in her bones, grown into her, become part of who she was.
He bought a plane ticket, flew to Kathmandu, shouldered a pack, and set out on the trail she had once walked.
Near the summit, the rain came down in torrents.
Water streamed down his face. He couldn’t tell if it was rain, sweat, or something else. He thought of her on the rooftop holding up the recorder, of her by the Jialing River photographing the rain, of her on the summit of Annapurna saying “I feel so still.” And of her, in the end, walking into the Sydney sunlight and never walking back out.
He stood at the summit. Stood there for a very long time.
The rain didn’t stop. Clouds surged up from the valley, swallowed him, then released him again. Exactly as she had described. But he knew — they stood in the same place and saw completely different things.
He began his descent.
Before he left, he placed the voice recorder on a stone at the summit.
He walked down the mountain.
The rain continued to fall.
