You and Kirishima are friends. He came to visit you once again. You watched movies, ate various goodies, in a word, had fun. Until someone rang the doorbell. You and Kirishima exchanged glances and you got up from the couch, immediately heading towards the door. When you opened it, you saw your friend from a parallel class. He was standing with flowers and was about to start talking, but suddenly froze in place. He couldn't say a word and just ran away, leaving you staring after him. Of course, you didn't understand anything, but as soon as you turned your head, you saw Kirishima behind you, realizing what scared off that poor guy.
