In Xia Tian, a melancholy and handsome young man studying art works as a marriage agent in a dating agency in order to make money. He unexpectedly meets the innocent and silly Yun Duo, who turns out to be a lost fairy. She confidently moves into Xia Tian and Xiaojie's "mansion". At that time, in the summer, Chu Yi, who was studying abroad, fell in love with her. Under Yun Duo's charming beauty was a wounded heart and an amnesiac mind. After the beautiful encounter, there was hesitation, lingering regret and reluctance.
Xia Tian's good friend Xiaojie is an equally talented and uninhibited young man who loves rock music and art. He betrayed his gay friend Tuo just because he found an eternal true love. But the road of betrayal is sprinkled with blood, drugs, chaos and tears.
Xia Tian's half-brother, Xia Lian, is the Ice Prince in the music world. He is involved in those lingering emotional entanglements. The shadow of Xia Tian's childhood lingers, shrouding both him and Chu Yi in a haze.
Everything happened in this burning summer that is destined to pass away and never come back again. When you look up at the sky, even though your tears have turned to ashes and your youth is broken. After all, there were snow-white clouds floating by.
