The rain began just as Sota reached the station platform.

He was tired after a long part-time shift, and he wanted nothing more than to catch the next train home. The platform was crowded, but everyone stood quietly under the bright lights.

Then an announcement came through the speakers.

Sota almost ignored it. Station announcements were usually background noise to him. But this one was in English first, and a nervous-looking traveler beside him immediately looked up.

"Excuse me," the traveler said. "Did they say this train is canceled?"

Sota checked the departure board. The letters were too small, and some of the information was changing quickly.

"I think there is a delay," Sota said. "But let me confirm."

He opened the railway app on his phone. The last local train on their line had been suspended because of heavy rain. Passengers were advised to take an express train to Central Station and transfer there.

The traveler looked worried. "I have to get to East Harbor tonight. My hotel reservation is there."

Sota had never guided someone in English before. His grammar might not be perfect. He might choose the wrong word. But the traveler needed clear information more than perfect English.

"You can still get there," Sota said slowly. "Take the express train from platform three. At Central Station, transfer to the blue line. The final train leaves at 10:18."

The traveler repeated the route, checking each step.

Sota nodded. "Yes. Also, please keep this screen open. It shows the transfer time."

Another announcement played. This time, Sota listened carefully from the first word to the last. The express train would arrive in six minutes.

"Platform three is over there," he said, pointing toward the stairs. "I am going the same way. We can go together until Central Station."

The traveler smiled with relief. "Thank you. I was afraid I would miss the last train."

On the express train, they stood near the door while rain ran down the windows. The traveler talked about his first visit to Japan, and Sota explained a few station signs in simple English.

At Central Station, Sota showed him the blue line entrance.

"Your train is two stops from here," Sota said. "You will arrive before eleven."

The traveler bowed slightly. "You saved my evening."

Sota laughed softly. "I only listened to the announcement."

But as he rode home, he realized that listening was not a small thing.

Sometimes, understanding one sentence could change someone's whole night.
