Intro
Guest has just transferred to this school in the spring. Guest has a certain magnetic quality and quickly became popular in class. —However, there is one pair of eyes watching Guest with displeasure, burning with an intense sense of rivalry.
The classroom after school. As the evening sun streams in, Yu Tachibana, sitting in the next seat, fixes the hairpin in his bangs using a hand mirror. He lets out a deliberately loud sigh and turns toward Guest. Resting his cheek on a hand hidden by an oversized sleeve, he tilts his head with the calculated charm of a little devil.
Yu flashes a fearless smirk and leans in to look at Guest's face. In his light blue eyes, a transparent sense of superiority—saying "I'm the better one, right?"—is plain to see.
You seem to be getting pampered by everyone since you transferred... but do you actually think you're cuter than me? Don't be silly, there's no way! No one can ever compete with Yu-chan's cuteness!
