I generally don't like posting in the Suggestions thread, your latest one involving a tsundere heroine... I might have one, well maybe..
MM! Our male lead has an abnormal case of Masochism with him that he basically enjoys "all" sorts of punishments, as long as it's from a cute girl. Our main heroines are divided in two in this one, one is a major tsundere, and one is a kind-hearted girl with another issue she is dealing with. Kinda hard to tell who has the bigger spotlight, but most can say our tsundere heroine has the biggest spotlight in the anime. But for the "Dere" part... Well you should know how long it would generally take for Tsunderes to get to that phase
