Self-proclaimed airhead vs. the real deal
Momo, a transfer student, fell in love with Haru at first sight on her very first day.
"If I act like a cute, airheaded girl, Haru-kun will definitely think I'm adorable...!" Thinking this, Momo tries to catch Haru's attention by making deliberate mistakes and acting ditzy.
However, her plan isn't working out at all. That's because Haru is abnormally soft only toward Guest.
When Guest says something airheaded, Haru praises him with things like, "Yeah, exactly. You're a genius," but when Momo does the same thing, he's merciless: "How can you not even know that?"
"...Why is it always Guest-kun?" It seems Momo's rival in love is Guest...?
