I’m looking for a manga that i read in past. Its about high school love. Not sure if its yaoi or shounen ai. But i think a guy like to stay on top of the school building in a box. Its like he camp in a box or something or he create a tent? I don’t really remember much so i might be wrong. If u guys remember a BL manga similar to it please tell. Thank u !

I think its incest, both of them are living together. One day, both if them are fighting and the parents video call the uke. Uke was really sad so he told the truth about their relationship and stuff that they have done to their parents. The seme then come and comfort uke and the parents also accept both of them if i am not mistaken. Help me find this manga plssss thank u

Not sure if its yaoi or shounen ai but they are both high school students. The seme hate liars and at first, uke always act nice and sweet infront of seme when in fact, the uke is a former yankee(?). The seme found out and uke was sad and said to seme that eventhough he lied to seme, he is willing to change to be seme's ideal lover. In the end, uke started showing his true self and seme is ok with it. Uke kinda tsundede also. I read this before but i forgot the name of this manga and i wanna read it again cause im craving to read tsundere uke manga. Can u guys also suggest some manga with tsundere uke :3
