Normally I don't change tags without reading things to confirm, but this time I'm going to trust you (and MangaUpdates' tags) because rapey love-triangles with brothers is most definitively not-my-cup-of-tea.
@Pokari , Thank you so much! Especially since I posted that before I was aware that there is an official "report" option for things like missing tags, so I would just leave it in the comments. I've gotten sarcasm from others for doing such, so I really appreciate you!
XD I'm just an ordinary reader who happens to have been around back when they were handing out edit-entry credentials to anyone who asked. I'm sorry you've gotten snarked at, that sounds unpleasant.
