Two male protagonists, Qi Xi and Jian Xiao, cold and tough-tongued vs. Gentle and shrewd.
A dream brought Qi Xi into a dream of parallel time and space. Every night he would meet the person who still gave him a headache, Jian Xiao. In the dream, they teased each other (Qi Xi: Does anyone care?), Disliked each other (Jian Xiao: It was obviously you who disliked me unilaterally, but I have always been loyal to you. Qi Xi: Get lost, I'm going to vomit.), And even redeemed each other...
Concept: Fate comes early rather than by chance
