Koshiro's co-worker Chidori sees him under a blooming cherry tree and questions him on what he has decided to do about his relationship with his sister (we know he has already decided but Chidori doesn't)
Chidori: "What are you going to do from now on?"
Koshiro: (Pauses for several panels) "I'm sorry to worry you..."
Chidori: "It's not like that at all."
Koshiro: "It's so pretty."
Koshiro: "Cherry blossoms. Until now, I ... never noticed things like this."
