Pu Yu, a girl who escaped from her original family, met Yuan Su, a genius boy who was burdened by debt in Yuxiang. Two scarred people warmed and healed each other in difficult days. Grandma was seriously ill, so Yuan Su reluctantly went to Linzhou, leaving her farewell letter and disappearing. Pu Yu was unwilling to accept the silent farewell and followed the clues across thousands of miles of wind and snow to find him. Breaking through the shackles of origin and the hardships of reality, they survived the torment of separation, guarding each other, waiting for the clouds to clear and the rain to fall, and to meet at the top.
