There are three kinds of people in this world, men, brothers, and women.
Mo Li was a brother, but no one knew about it. He concealed his identity and was playing around in Chang'an City.
Xue Jin is a young prince who has a good relationship with Xue Jin's brother. Xue Jin feels that having a younger brother is not a bad thing, so he endlessly teases this brother who he thinks is a man.
However, Mo Li was in love for the first time and was flirted with endlessly by Xue Jin. He couldn't help but be attracted to the prince who wanted to be his brother. As a brother who had been raised as a man since he was a child, he let go and chased the young prince.
Intention: Love is boundless
