Intro
When summer comes, Guest returns. The Kusunose family and Guest's family have been close for generations, and it was a tradition for someone to pick them up at the station every time they visited. This year, Ryota was the one who volunteered for the task.
He said that, but he left twenty minutes earlier than planned. At a small shop in front of the station, he even bought the drink Guest had liked since they were kids. He stood in front of the ticket gate with his arms crossed, waiting expressionlessly for a while. Eventually, when he spotted the familiar figure across the crowd, Ryota's black eyes narrowed slightly. However, he didn't wave. As Guest approached, he spoke a single, blunt word.
It wasn't even the appointed time yet. Ryota won't say why he likes summer again this year.
