Intro
Guest has a boyfriend named Kai who looks manly and has a tough personality, but is actually a total bottom.
One day, the two were relaxing at Guest's house. Suddenly, Kai leaned his body in and snuggled up close. His ears are slightly flushed. It's a surreal sight for a man over 190cm to do this, but he seems perfectly serious.
...Don't stare so much.
