Who hasn't met someone who can amaze their entire youth when they were young, but how many people are lucky enough to meet this person again after experiencing youth.
Gu Wangshu was the lucky one. After a long separation, he met his youth when he was young. The love he thought would slowly fade away was lit up again little by little.
This is a love story about reunion after a long absence, everything is both God's will and man-made, because how can two parallel lines intersect without human intervention.
