He was left feeling like he’d swallowed a lump of something he shouldn’t have, something he couldn’t spit out, or digest. He stayed home the whole day waiting for the phone to ring. His mind was unfocused, and he was unable to concentrate. He’d left repeated messages with his friends’ families, telling them he was in Nagoya. Usually his friends would call right away and cheerfully welcome him back, but this time the phone remained implacably silent.

Tsukuru thought about calling them again in the evening, but then decided not to. Maybe all of them really were at home. Maybe they didn’t want to come to the phone and instead were pretending to be out. Maybe they had told their families, “If Tsukuru Tazaki calls, tell him I’m not here.” Which would explain why their family members sounded so ill at ease.

But why?

He couldn’t imagine a reason. The last time the five of them had been together was in early May, during the Golden Week holidays. When Tsukuru had taken the train back to Tokyo, his four friends had come to the station to see him off, giving him big, hearty, exaggerated waves through the window as the train pulled away, like he was a soldier being shipped off to the ends of the earth.

After that point, Tsukuru had written a couple of letters to Ao. Shiro was hopeless with computers, so they normally relied on letters, and Ao was their contact person. Tsukuru always addressed the letter to Ao, who made sure that the letters circulated among the others. That way Tsukuru could avoid writing individual letters to everyone. He mainly wrote about his life in Tokyo, what he saw there, what experiences he had, what he was feeling. But always, no matter what he saw or did, he knew he would be having a much better time if the four of them were there to share the experience with him. That’s how he really felt. Other than that, he didn’t write anything much.

The other four wrote letters to him, jointly signed, but there was never anything negative in them. They just reported in detail on what they’d been up to in Nagoya. They’d all been born and raised there, but they seemed to be enjoying their college lives. Ao had bought a used Honda Accord (with a stain on the backseat that looked like a dog had peed there, he reported, the kind of car five people could easily ride in, as long as none of them was too fat), and all of them piled into the car to take a trip to Lake Biwa. Too bad you couldn’t go with us, Tsukuru, they wrote. Looking forward to seeing you during the summer, they added. To Tsukuru, it sounded like they meant it.

That night, after he still hadn’t heard from his friends, Tsukuru had trouble sleeping. He felt agitated. Random, senseless thoughts flitted around in his head. But all these thoughts were just variations on one theme. Like a man who has lost his sense of direction, Tsukuru’s thoughts endlessly circled the same place. By the time he became aware of what his mind was doing, he found himself back where he’d started. Finally, his thinking process got stuck, as if the folds of his brain were a broken screw.

He remained awake in bed until 4 a.m. Then he fell asleep, but he woke up again shortly after six. He didn’t feel like eating, and drank a glass of orange juice, but even that made him nauseous. His lack of appetite worried his family, but he told them it was nothing. My stomach’s just a little tired out, he explained.

Tsukuru stayed at home that day, too. He lay next to the phone, reading a book, or at least trying to. In the afternoon he called his friends’ homes again. He didn’t feel like it, but he couldn’t just sit around with this baffling, disconcerting feeling, praying for the phone to ring.

The result was the same. The family members who answered the phone told Tsukuru—curtly, or apologetically, or in an overly neutral tone of voice—that his friends weren’t at home. Tsukuru thanked them, politely but briefly, and hung up. This time he didn’t leave a message. Probably they were as tired of pretending to be out as he was tired of trying to contact them. He assumed that eventually the family members who were screening his calls might give up. If he kept on calling, there had to be a reaction.

And eventually there was. Just past eight that night, a call came from Ao.

“I’m sorry, but I have to ask you not to call any of us anymore,” Ao said abruptly and without preface. No “Hey!” or “How’ve you been?” or “It’s been a while.” I’m sorry was his only concession to social niceties.

Tsukuru took a breath, and silently repeated Ao’s words, quickly assessing them. He tried to read the emotions behind them, but the words were like the formal recitation of an announcement. There had been no room for feelings.

“If everybody’s telling me not to call them, then of course I won’t,” Tsukuru replied. The words slipped out, almost automatically. He had tried to speak normally, calmly, but his voice sounded like a stranger’s. The voice of someone living in a distant town, someone he had never met (and probably never would).

“Then don’t,” Ao said.

“I don’t plan on doing anything people don’t want me to do,” Tsukuru said.

Ao let out a sound, neither a sigh nor a groan of agreement.

“But if possible, I do want to know the reason for this,” Tsukuru said.

“That’s not something I can tell you,” Ao replied.

“Then who can?”

A thick stone wall rose. There was silence on the other end. Tsukuru could faintly hear Ao breathing through his nostrils. He pictured Ao’s flat, fleshy nose.

“Think about it, and you’ll figure it out,” Ao said, finally.

Tsukuru was speechless. What was he talking about? Think about it? Think about what? If I think any harder about anything, I won’t know who I am anymore.

“It’s too bad it turned out like this,” Ao said.

“All of you feel this way?”

“Yeah. Everyone feels it’s too bad.”

“Tell me—what happened?” Tsukuru asked.

“You’d better ask yourself that,” Ao said. Tsukuru detected a quaver of sadness and anger in his voice, but it was just for an instant. Before Tsukuru could think of how to respond, Ao had hung up.

“That’s all he told you?” Sara asked.

“It was a short conversation, minimalist. That’s the very best I can reproduce it.”

The two of them were face-to-face across a small table in the bar.

“After that, did you ever talk with him, or any of the other three about it?”

Tsukuru shook his head. “No, I haven’t talked to any of them since then.”

Sara’s eyes narrowed as she gazed at him, as if she were inspecting a scene that violated the laws of physics. “None of them?”

“I never saw any of them again. And we’ve never spoken.”

“But didn’t you want to know why they suddenly kicked you out of the group?”

“I don’t know how to put it, but at the time nothing seemed to matter. The door was slammed in my face, and they wouldn’t let me back inside. And they wouldn’t tell me why. But if that’s what all of them wanted, I figured there was nothing I could do about it.”

“I don’t get it,” Sara said, as if she really didn’t. “It could have been a complete misunderstanding. I mean, you couldn’t think of any reason why it happened? Didn’t you find the whole thing deplorable? That some stupid mistake might have led you to lose such close friends? Why wouldn’t you try to clear up a misunderstanding that might have been easily rectified?”

Her mojito glass was empty. She signaled the bartender and asked for a wine list, and, after some deliberation, she chose a glass of Napa Cabernet Sauvignon. Tsukuru had only drunk half his highball. The ice had melted, forming droplets on the outside of his glass. The paper coaster was wet and swollen.

“That was the first time in my life that anyone had rejected me so completely,” Tsukuru said. “And the ones who did it were the people I trusted the most, my four best friends in the world. I was so close to them that they had been like an extension of my own body. Searching for the reason, or correcting a misunderstanding, was beyond me. I was simply, and utterly, in shock. So much so that I thought I might never recover. It felt like something inside me had snapped.”
