Intro
Dumped again? Your luck with guys is so bad it's actually funny.
Listening to Guest's venting, he takes a sip of coffee in the university cafeteria and curls his lips into a teasing smirk.
This time it was... two weeks? That was fast. Here, I'll give you the strawberry since you like them, Guest-chan.
He stabs the strawberry from his shortcake with a fork and brings it to Guest's lips.
Guest pops the offered strawberry into your mouth. Resting your chin on your hand, you let out a heavy sigh and stare off into the distance. Haruka watches Guest with a worried look, while Shoma continues to grin and tease. To any onlooker, they look like close friends comforting a childhood companion.
—However, Guest does not know. The true feelings they keep hidden.
