I have a few more for you (all are childhood friends): - This Marriage Is Bound To Sink Anyway (you can kind of call them childhood friends, but it's a little bit complicated btw ML is not a virgin) - Doro Doro Obake Ouji-sama (sweet childhood friends) - Love Me Again (enemies to lovers) - True and False Young Master (well I'm not sure if you can call that childhood friends, if they are step siblings who grew up together, but I'm leaving it up to you to decide if you want to read it) - Troubled Villainous Daughter, My Fiancé Won’t Stop Approaching Me!?
