"A piece of paper in the woods makes the mountains and rivers clear."
Yi Qing, a little bully who was fearless, had an older brother when he was 5 years old. He and his nominal brother hated each other and were against each other.
Lin Xu, a person who has seen through the world since he was a child, met a tyrannical and domineering little bully when he was 6 years old. From then on, he started a road of falling in love, killing each other, and hating each other.
The two people who fell in love and killed each other, after learning about each other's past, finally put aside their hatred and became brothers who are not related by blood.
However, there will always be some setbacks and difficulties when young people are just starting to fall in love.
(There are three pairs of CPs in it, the main characters are sour and the relationship between the characters is somewhat complicated.)
