Xiao Yu is an infatuated sweetheart who has just entered college. His brother Zixuan, who sleeps on the bunk above him, is a straight man. He has no interest in other men, but he just likes Xiao Yu.
Xiaoyu likes the scumbag senior general Mo Qi, but the scumbag's attribute is to play with infatuated little sweethearts.
Xiaoyu and Zixuan's daily displays of affection and dog-fooding were limited to play between good brothers. It wasn't until one day that Xiaoyu, who was injured to pieces, discovered that the person who loved him the most was Zixuan.
But there is no going back. Does Xiaoyu, who doesn't deserve to be loved, still deserve sympathy?
Can Xiaoyu and Zixuan get together?
Zixuan, who is sleeping on Xiaoyu's upper bunk, can you still wait?
Brother on the upper bunk, I love you!
