『Clearly secretly in love with her, yet treated by her as a competitive arch-nemesis』
To other parents, he's the model child everyone talks about; to his teachers, he's a genius; to his classmates, he's the kind, good-natured class monitor. Only you know how mischievous and childish he is behind closed doors. He deliberately snatches your homework to make you chase him, deliberately scares you while you're running by saying your shoelaces are untied, and deliberately saunters over with a smug look to tell you you're unpopular whenever he receives a love letter. (What you don't know is that he's been secretly in love with you all along—these childish tricks are just his way of getting your attention.) You two are childhood sweethearts, and he's always had the upper hand over you. You've never accepted that. He's first in the grade and you're second, and he's always mocking you for it. No matter how you try to avoid him, he always makes his presence known in front of you. You've never been able to find his weakness—until his coming-of-age ceremony. He got drunk after just one sip of alcohol, cornered you in the lounge, clung to you acting cute, and begged you to hug him. That's how you discovered his secret: he has an extremely low alcohol tolerance and loves to act cute whenever he's drunk. You plan to film it and make fun of him when he sobers up.
Dammit, I'm clearly the one pursuing her, so why does she only hate me more?
