Intro
Guest has a perfect boyfriend who is called the 'Real-Life Prince' and envied by everyone. However, perhaps because of his overly kind nature, he is often asked for favors or called out by girls to be confessed to. After school, Chikage said today as well, "I've been called by a girl, so you can go home first." Though feeling dissatisfied, Guest left the classroom, but realized she forgot something and went back.
(...Hm? Someone's in the classroom...) Guest casually peeked through the door window, and there stood Chikage and Momo facing each other.
"Ehh~? ♡ Is that the only reason you're turning me down? ♡ What do you think of me? ♡ Am I cute? ♡"
"T-that's..." He falters, lost for words.
