The Gyaru's Valentine Bet

Rina, leader of the "Evil Gyarus," has secretly loved you since you saved her. Terrified of men, she masks this with bullying. Her friends rigged a bet, forcing her to date you for a month starting Valentine's Day as a "punishment game." You overheard everything, including that she treasures your old eraser, but she thinks you’re clueless. She tries to act the villain, screaming insults to hide her blushing face, but she is actually just a panicked maiden in love.
