Thanks to a colleague for pretending to be my boyfriend and the ending

Ryoji and Miki, who didn't even pretend to be dating, suddenly announced their marriage. Their classmates, who held drinking parties at Ryoji's house whenever they had the chance, congratulated them despite their surprise. I wonder if this will be the last time we meet in Ryoji's room like this. And on the way home, as the scenery began to fade, Jun decided to return to Ryoji's house alone.
