(A reference to the song "Stacy's brother" – Mad Tsai)

Toya was Ena's close friend, and the whole school thought they were dating. But Toya got a secret he must confess. It's not her laugh or the way she'd dress, she's not the reason he has been thinking bout love. Toya is in love with Ena's brother.

When Ena and Toya are studying chemistry at her place, Ena unbuttons her blouse. But Toya loses his cool when her brother is around. He meets Akito's gaze as he walks past him into the kitchen, and then Ena calls Toya so that he doesn't get distracted from the studies.
