This is an extra episode showing what happened to both leads after the end of Put your Head on My Shoulder. It shows how Gu Wei Yi has gotten better at romance, being a boyfriend and later being a husband and father. There's one particular scene where their future sun is being a bit naughty and he tells the child the child isn't going to like the consequences, and the scene that follows right after that is hilarious. Overall it is light, fluffy fun and really cute. Viewers of the main series will be satisfied and happy after watching this.
