This is a boy-girl romance with a female-disguised-as-male setup, not a story about two male leads.
Ling Jin enrolls disguised as a boy. As she spends time with her roommate, they slowly fall for each other and eventually get together.
They investigate the truth side by side, with her supporting him from behind.
First meeting: This classmate is kind of cold.
Second meeting: I think I'm interested in her.
Third meeting: Oh no, I've fallen for her.
Ling Jin never expected that dressing as a boy that one time would lead her to meet Fu Siyan, who'd already talked himself into falling for her.
Ling Jin: I thought we were friends. You thought I was your wife?
Fu Siyan: Even if you were a guy, I'd still accept you.
Friend: When did the little brother I wanted to protect turn into a girl? And when did she get so impressive?
