Secret Crush Turned True Love

Her adoptive older brother suddenly comes back from overseas and asks to "share a place" with her?

He even says he's asexual, so she can "relax"?

But she's had a crush on him for years. What is she supposed to do?

Help him rediscover his feelings for women?

Hey, hey, he hasn't even gotten her permission, so why is he kissing her already?

Her mom gives her the terrible idea of seducing him, and the result is...

"You jerk! Ahhh! How could you say you were asexual before?"

"You were just the perfect 'medicine' for me, so I got cured..."

- Devoted to each other, one-to-one pairing, happy ending. Mutual pining.

- The male and female leads are not related by blood and aren't on the same household registration.
