“Farewell, Tsukuru Tazaki. Have a safe trip home,” Eri said as they said goodbye. “Don’t let the bad elves get you.”

“Bad elves?”

Eri’s eyes narrowed, her lips curling mischievously like in the old days. “It’s a saying we use a lot here. ‘Don’t let the bad elves get you.’ So many creatures have lived in these forests since olden times.”

“Understood,” Tsukuru laughed. “I’ll keep an eye out for them.”

“If you get a chance,” Eri said, “let Ao and Aka know that I’m doing well here.”

“I will.”

“I think you should go see them sometimes. Or get together, all three of you. For your sake. And for theirs.”

“I agree. That might be a good idea,” Tsukuru said. “It’d be good for me, too,” Eri said. “Even though I can’t be with you.”

Tsukuru nodded. “Once things settle down, I’ll make sure to do that. For your sake, too.”

“But it’s strange, isn’t it?” Eri said.

“What is?”

“That amazing time in our lives is gone, and will never return. All the beautiful possibilities we had then have been swallowed up in the flow of time.”

Tsukuru nodded silently. He thought he should say something, but no words came.

“Winter here is really long,” Eri said, gazing out at the lake, sounding as if she were addressing herself far away. “The nights are so long and it seems never-ending. Everything freezes solid, like spring will never come. All sorts of dark thoughts come to me. No matter how much I try to avoid them.”

Still no words came to him. Tsukuru silently followed her gaze to the surface of the lake. It was only later, after he boarded the direct flight back to Narita and had buckled his seat belt, that the words came, the words he should have said. The right words always seemed to come too late.

He turned the key and started the engine. The four-cylinder Golf engine awoke from its short sleep and slowly found its rhythm.

“Goodbye,” Eri said. “Be well. And make sure you hold on to Sara. You really need her.”

“I’ll try.”

“Tsukuru, there’s one thing I want you to remember. You aren’t colorless. Those were just names. I know we often teased you about it, but it was just a stupid joke. Tsukuru Tazaki is a wonderful, colorful person. A person who builds fantastic stations. A healthy thirty-six-year-old citizen, a voter, a taxpayer—someone who could fly all the way to Finland just to see me. You don’t lack anything. Be confident and be bold. That’s all you need. Never let fear and stupid pride make you lose someone who’s precious to you.”

He put the car into drive and stepped on the gas. He stuck a hand out the open window and waved. Eri waved back. She kept on waving, her hand held high.

Finally she disappeared in the trees. All he saw in the rearview mirror now was the deep green of a Finnish summer. The wind seemed to have picked up again, and small waves rippled on the surface of the lake. A tall young man in a kayak appeared on the water, slowly and silently slipping through the water like some gigantic whirligig.

I’ll probably never be back here again, Tsukuru thought. And never see Eri again. We each have our paths to follow, in our places. Like Ao said, There’s no going back. Sorrow surged then, silently, like water inside him. A formless, transparent sorrow. A sorrow he could touch, yet something that was also far away, out of reach. Pain struck him, as if gouging out his chest, and he could barely breathe.

When he reached the paved road, he steered the car to the side, switched off the engine, leaned against the steering wheel, and closed his eyes. His heart was racing and he took slow, deep breaths. And as he inhaled, he suddenly noticed a cold, hard object near the center of his body—like a hard core of earth that remains frozen all year long. This was the source of the pain in his chest, and the difficulty breathing. He had never known, until this moment, that such a thing existed inside him.

Yet it was this pain, and this sense of being choked, that he needed. It was exactly what he had to acknowledge, what he had to confront. From now on, he had to make that cold core melt, bit by bit. It might take time, but it was what he had to do. But his own body heat wasn’t enough to melt that frozen soil. He needed someone else’s warmth.

First he had to get back to Tokyo. That was the first step. He turned the key and started the engine again.

On the road to Helsinki, Tsukuru prayed that Eri wouldn’t be caught by any bad elves of the forest. All he could do at this point was pray.

Tsukuru spent the remaining two days of his trip wandering the streets of Helsinki. It rained occasionally, just a light sprinkle that didn’t bother him. As he walked, he thought of many things. There was much he needed to consider, and he wanted to gather his thoughts before he returned to Tokyo. When he got tired of walking, or of thinking, he’d stop by a cafй and have a coffee and a sandwich. He got lost, not knowing where he was, but that didn’t bother him either. Helsinki wasn’t a huge city, and streetcars ran everywhere. And for him right now, losing sight of where he actually was felt good. On his last afternoon in the city he went to Helsinki Central Station, sat on a bench, and watched the trains come and go.

From the station he called Olga on his cell phone to thank her. I found the Haatainens’ house all right, he told her, and my friend was definitely surprised to see me. And Hдmeenlinna was a beautiful town. That’s great, Olga replied. Wonderful. She seemed genuinely happy for him. I’d like to take you out to dinner to thank you, he said. I appreciate the invitation, Olga said, but today is my mother’s birthday and I’m having dinner with my parents at home. But please be sure to tell Sara hello from me. I will, Tsukuru replied. And thank you for everything.

In the evening he had seafood and half a glass of chilled Chablis at a restaurant that Olga had recommended near the harbor. As he sat there, he thought about the Haatainens. Right now the four of them must be seated around their table. Was the wind still blowing on the lake? And what was Eri thinking about, at this very moment? The warmth of her breath still grazed his ear.

He arrived back in Tokyo on a Saturday morning. He unpacked, took a leisurely bath, and spent the rest of the day busy with random tasks. As soon as he got back, he thought of calling Sara, and had actually picked up the phone and dialed her number. But then he put the phone down. He needed more time to think. It had been a short trip, but so many things had happened. It still felt unreal to be back in the middle of Tokyo. It felt like just a short time ago he’d been beside the lake in Hдmeenlinna, listening to the transparent sound of the wind. No matter what he said to Sara, he needed to choose his words carefully.

He did the laundry, glanced through the newspapers that had piled up, then went out before evening to shop for food, though he had no appetite. Probably because of jet lag, he got terribly sleepy while it was still light out, lay down in bed at eight thirty, and fell asleep, only to wake up before midnight. He tried reading the book he’d started on the plane, but his mind was still a blur, so he got up and cleaned the apartment. Just before dawn, he returned to bed, and when he awoke it was almost noon on Sunday. It looked like it was going to be a hot day. He switched on the AC, made coffee, and had a cup with a slice of toast and melted cheese.

After he took a shower, he phoned Sara’s home. The phone went to voicemail. Please leave a message after the beep, the message said. He hesitated, then hung up without saying anything. The clock on the wall showed that it was just after one. He was about to call her cell phone, but thought better of it.
