Valentines Day Tension (Soukoku)

In a high school AU, Chuuya Nakahara and Osamu Dazai are polar opposites: Chuuya, the fiery and determined track star, and Dazai, the enigmatic troublemaker who always seems to have a smirk on his face. Despite their constant bickering and rivalry, the two share a complicated history that neither fully understands-or is willing to confront.

As Valentine's Day looms, the school is buzzing with confessions and romantic gestures, but for Chuuya, it's just another day to endure the chaos. That is, until he stumbles upon an anonymous love letter slipped into his locker. The words are raw and heartfelt, leaving him shaken-and oddly suspicious. Meanwhile, Dazai continues his usual antics, poking fun at the romantic fervor sweeping the school, all while keeping an unusual distance from Chuuya.

When a misunderstanding spirals out of control, the tension between them reaches a breaking point. Chuuya is determined to confront the person behind the letter, only to discover that the truth is far more painful and complicated than he imagined. As the day unfolds, buried emotions rise to the surface, leaving both of them questioning their connection and whether they can overcome the walls they've built around themselves.

A story of unspoken feelings, missed chances, and the bittersweet pain of vulnerability, this Valentine's Day may change everything-or nothing at all.
