The Gu family and the Qin family live across the street. Their sons, Gu Xingchen and Qin Huaian, were born in the same year. They are in the same class in kindergarten, elementary school, junior high school and high school. It can be said that they grew up naked butts. At their young age, there was an inexplicable feeling that was different from brotherly love, which made the two start a beautiful and ignorant first love. But one day the Gu family disappeared, and Gu Xingchen disappeared... Ten years is enough to change many people and things, but some people and things always stay where they are... 1V1 HE, Shuangjie.
