Tsukino Usagi is a cute girl who loves fantasy and romance. She is not very bright and a bit careless, so she has been strictly disciplined by her parents since she was a child. However, as a result, Xiao Nizi has no experience in love but is full of all kinds of exaggerated fantasies about love. After much hard work, he finally got into a prestigious school with his gymnastics skills. By chance, he met the cold yet gentle floor guard who was a top student. The two developed a mutual affection and progressed smoothly. But Prince Wei is very good-looking, but has an "ordinary" personality. It's very comfortable to be with him, but it gets really boring after a long time. There are none of the romantic scenes that Tsukino Usagi imagines in love, nor the touching experiences of "the hero and heroine finally live a happy life after going through twists and turns"... Is it true that we have not tasted "Youth Love Song" and are about to enter the daily life of an "old husband and wife"? How should Wei Tu and Wei Tu resolve this conflict? Can they make it to the end?
