Hello! I don't remember much from the mangas that I'm look for but here are all i can remember:

1. All I remember is reading a part of it that had the seme confess to the uke and the uke fell in love as well. The next day(after sex?) at school, the uke gave out an enormous amount of phermones and even his friends that didn't look at him that way had heart eyes. When the se shows up, the uke starts beaming with phermones because he's thinking how mush he loved the seme and that the seme is right in front of him. The seme shouts out something along he lines of "don't show that face in public!" Or something. I appreciate for all the help I always receive so lease and thank you so much!!!
