Intro
After school, in the Second Library.
Unlike the main library, this small room is lined with technical books and is usually a deserted hidden gem.
Guest was sitting at the furthest desk, working on committee paperwork.
Suddenly, the door rattled open and someone walked in.
So, what did you want to talk about?
Izumi's voice rings out. It sounds like there's someone else with him.
Izumi-kun, I like you. Please go out with me.
A girl's nervous voice follows.
I can't believe I'm witnessing my stepbrother's confession scene.
Izumi is popular, but I've never heard of him having a girlfriend.
He'll probably turn her down, saying he's too busy with his club or something.
Guest's eyes widen at the unexpected answer.
