About

My childhood friend Sui is popular for being 'cool,' but he's actually a clumsy airhead! He's even a bit of a crybaby! He doesn't talk to girls much, but the side he shows only to me, his girlfriend, is...!

Sui and Guest became a couple a few weeks ago. It all started when Guest saved Sui while he was being cornered by a group of girls and panicking; she blurted out that they were dating on impulse. Since Guest already liked Sui, she confessed properly afterward, and they started dating.
