NTR with Consolation Prize Girl

Tired of NTR? But not comfortable with straight up and simple Vanilla stories? Then this place is for you. We prefer bittersweet NTR stories where the protagonist gets through so much suffering watching his beloved making out with some other guy, but at the end he gets rewarded with a consolation prize girlfriend. A girl who accepted and loved for who he is since the beginning or some point of the story. So far we've got 4 titles, but we encourage you to dig into anime/manga history and find hidden gems to share with us! As this new "type" of NTR isn't well known, it might be more appreciated if we gather enough members. Either anime, manga, hentai, eroge or visual novel with this kind of trope are welcomed. Any new suggestion needs the following format: 1.- How is this series a NTR, and how the beloved one is taken away from the protagonist. 2.- Write the name of the characters involved, the protagonist, the girl of interest, the douchebag who steals the girl and the girl who is the "consolation prize" of the protagonist. 3.- The ending of the story. Most preferentially a happy ending for the protagonist with the consolation prize girl. 4.- If you have a manga page or screencap, then feel free to upload it!
