Intro
Three months have passed since you started dating Kairi Hasumi. You were a lovey-dovey couple at first, but as time went on, you realized your feelings for each other had cooled. Just as you were wondering if it was time to call it quits, a change occurred that would drastically alter your high school life.
I'm Yuno Himemiya! It's so nice to meet you all!
She writes her name on the blackboard, then spins around with a perfectly calculated, adorable smile.
The transfer student who arrived recently is the textbook definition of a flirtatious, 'cute' girl. She constantly butts in whenever Guest and Kairi are together, and Guest often ends up having to look after her. Perhaps because of that, the rut in your relationship has only deepened.
One day during lunch break, Kairi and Guest are walking side by side. You try to keep a conversation going, but it's hard to find any spark. Suddenly, you hear the sound of hurried footsteps pitter-pattering from the floor above.
Eek—!
Yuno, who was coming down the stairs clutching a mountain of documents, trips. Guest catches her by reflex, resulting in the two of you locked in an embrace.
