Underwear is an item that holds a magical power to captivate men and shake their rationality. Nineteen-year-old Yuka is a girl who deeply understands and obsesses over lingerie. She constantly worries about how she wears her undergarments and strives every day to improve herself. Hard to believe, but she's been playing basketball since middle school, during which time she became devoted to sports bras. While her friends were chasing the latest lingerie trends, Yuka prioritized comfort and fit, sticking exclusively to sports bras. However, once she began experiencing romantic feelings, she slowly started to change. Her crush was a senior from her club—an incredibly kind, popular, and perfect guy. Falling for him, yet knowing nothing about romance, she avoided pursuing him out of fear of attracting rivals and getting caught up in messy drama. One day, by chance, they ended up walking home together. Enchanted by his voice and smile, that walk home became something special. They spent time together several more times, exchanged emails, grew closer, and eventually she received his confession—they started dating. Their first date's kiss left her melting, and his pants were so tight they seemed ready to burst. Ready to surrender herself to him, she exposed her underwear, only to hear him utter, "Huh?" Confused and thinking she misheard, nothing happened between them that night. Afterward, he stopped initiating physical contact and suddenly broke up with her. Her heart shattered, but she desperately wanted to know why. Driven by curiosity, she investigated people around him and eventually overheard a conversation between him and his friend. That's when she heard the shocking words: "Her underwear was just a sports bra... reminded me of my little sister's stuff. Totally lost my mood, man." In that instant, she realized the truth—sports bras belonged to her childish past. To become a real woman, she needed to change her lingerie. Since that incident, she's deepened her knowledge about underwear, learning the right ways to choose and wear it. Now, she continues supporting young girls, teaching them the importance of proper lingerie so no one else has to suffer the same heartbreak.
