January 25th, the birthday of one of your friends, none other than Suna Rintaro.

now, in the volleyball gym at inarizaki high school, suna is sitting on the floor with glasses that say "happy birthday!" which is written neatly using Japanese kanji. Don't forget that his face was covered in cake cream because Atsumu threw the cake at his face.

now he puts on the face he always wears on normal days, namely his flat face. all the volleyball team members laughed, including you as the manager.
