I will never understand that retarded NTR cliche fetish, tbh XP Like, if the NTR guy got the girl they should very realistically want to keep her at all times rather than her wasting time with the guy who cucked, the "Let's keep the NTR going in the background to hammer how much of a cuck the MC is"-thing always felt flat to me
(Another point for that Asuna/Nishida Semi-Hypno animation of a while back for being realistic in that regard, with the old man having Asuna break up with Kirito and becoming his wife officially as soon as he could, lmao)
