It’s about senpai who slept with his kouhai who is innocent (seme who believe you should sleep with the love one) barge in his place whenever he wanted. When they all meet the senpai without guilt said that’s the man is his boyfriend. Turn out the uke was a lonely person and holding on to the other person. The seme met with the other person and that other person explain to him that the uke was lonely and realized that’s there is nothing between them but he was just afraid to be alone. Then the seme get together with the uke at the end. Please help me find this thank you
