Okay I'm sorry that I don't remember Much, so the Top along with his Hyung likes the Uke but their Father on the other hand is a very strict guy and homophobic, the Hyung got Uke first and the father found out later on and blamed and Humiliate Uke for it infront of the school and the Hyung don't dare step in to help cause he's scared of his Father, the Top on the other hand hurted Uke as kept quiet cause he's like it's non of his business cause he got with his Hyung when Uke went for him, Uke and the Hyung broke up, after some Time, the Top and Uke meet again and Top realised he also wants Uke but he knows Uke won't accept him cause he hurted him so he went and drug uke with a new Pink Drug that came out in his Lap which can delete a person's memories and there like the Start of the story where the uke can't remember anything and he lied that they're dating and somehow the uke remembered his memories at the end and teh tried to run away but this Time, the Top took a step further and stab the Uke with a syringe with a much stronger Drug that can Delete all his past Memories and there it ends with the Uke walking through the Hospital Hallway unfamiliar with Everything and the Top coming towards him and giving him flowers and introduce himself

Guys, the Top is a Total Narcissist Asshole, he ruined MC's life and Deleted his memories and the Ending is Worst
