Ryoji and Miki, who didn't even show signs of dating, suddenly declare their marriage! Ryoji's classmates, who used to gather at Ryoji's house for drinking parties, were surprised but congratulated the two. ``...Maybe this will be the last time we gather in Ryoji-kun's room like this.'' Even though they were in a celebratory mood, they decided that once they started a family, things wouldn't go the way they had before, so they drank until the morning and finally decided to call it quits. ...And then, on the way home when he started to feel pale, Jun made up his mind and headed back to Ryoji's house alone.
