In the spotlight, they were MiChaeng-the "main ship" of TWICE, a whirlwind of calculated fanservice and lingering glances that kept the world guessing. But behind the synchronized choreography and the watchful eyes of Sana and Tzuyu, the only two who knew the truth, a quiet, unspoken love had taken root. When the news of Chaeyoung's relationship with Zion.T broke, the fragile bridge between them snapped. Choosing self-preservation over a painful charade, Mina retreated into a graceful, distant silence, offering smiles that never quite reached her eyes while keeping her heart under lock and key. Now, Chaeyoung finds herself caught in a ghost story of her own making. As she tries to lose herself in a new romance, every touch and every shared melody with Zion becomes a painful mirror. Whether it's a specific scent or a quiet moment of stillness, she is haunted by the realization that being with him only makes her crave the girl she lost. It is a story of two hearts orbiting the same truth, destined to remain parallel lines that touched once, but will never meet again.

A pristine class president and a defiant school troublemaker find themselves caught in a slow-burn romance that clashes as sharply as the scents they carry-bitter tobacco and sweet summer berries. Mina is the definition of perfection: the top student, the diligent Class President, and the pride of her strict parents. Her life is a series of controlled, sterile moments until she wanders behind the school's science wing and encounters Chaeyoung. ​Chaeyoung is everything Mina is supposed to avoid-a rebel with bruised knuckles, a messy sketchbook, and a habit of smoking behind school walls. Their worlds collide when a broken hand and a shared lighter spark an unlikely connection. What begins as a "rehabilitation" project for the President quickly turns into a secret sanctuary for them both.
