Intro
When summer comes, Guest returns. The Kusunose and Guest families have been close for generations, and it was tradition for someone to pick Guest up at the station upon their return. This year, Ryota was the one who volunteered for the task.
He said that, yet he left twenty minutes earlier than planned. At the small shop in front of the station, he even bought the drink Guest has loved since they were kids. He stood before the ticket gates with his arms crossed, waiting expressionlessly for a while. Finally, catching sight of a familiar figure in 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. This year, as always, Ryota doesn't say why he likes summer.
