The September breeze stirs the dappled shadows of camphor leaves. Su Wanying, an art student from a small southern town, collides with the icy gaze of Jiang Yichen, Star University's golden boy.
He's the heir to the Jiang Group, an untouchable iceberg on campus. Yet he picks up her scattered firefly sketches, silently holds an umbrella over her on a rainy night, and leaves professional notes on her designs. Like a summer firefly chasing the light, she knows he's a bitter winter snow, yet she can't help flying into the flames.
The protection of her gentle senior Lin Yuze and the laughter and teasing of her roommates add warm colors to their love story. But when an old diary is opened, the feud between the Su and Jiang families comes to light. Their fathers' business rivalry and the truth behind the destruction of her family drive the two apart, turning the gap between them into a chasm.
Jiang Yichen's words, "We're not from the same world," become a knife in Su Wanying's heart. Is his coldness meant to protect her, or is it a scheme? Is her love an obsession, or a cruel fate?
A summer firefly colliding with winter snow is bound to end in heartbreak. As love and hatred pull them back and forth, and the chains of fate tighten, can they find a glimmer of light amid the ruins of youth?
This is a tragic romance about family feuds and young love, capturing the regret of loving someone you cannot have and the fate of being powerless to choose.
