In their second year of high school, Tan Ze transfers back to a private school in his hometown and moves in with a friend of his aunt's.
His aunt's friend has a son named Yang Siqi, who attends the same high school as Tan Ze.
Yang Siqi has always been easy to get along with, so the two boys live and eat together in peace.
Not long after, Yang Siqi happens to learn why Tan Ze transferred, and hears that he is "homophobic."
Later, one morning, Yang Siqi opens his eyes to find himself in Tan Ze's bed... with his arms around the other boy.
Yang Siqi knows that he sometimes sleepwalks when he doesn't sleep well, but this is still ridiculous.
Yang Siqi: When I sleepwalk... I'm pretty obedient. Why didn't you make me leave?
Tan Ze: I did. You wouldn't go.
Knowing the other boy is homophobic, Yang Siqi thoughtfully suggests: In case it happens again, why not lock your door when you go to sleep?
Tan Ze gives him a look. No need.
Yang Siqi: ...Huh?
