If it were me in any of these situations I would not be able to stop saying STFU to everyone.
For example: "wHy ArE yOu StIlL hOlDiNg ThE bRa?!?!1111" "STFU, I've been holding it for less than a second, fuck off and let me put it down without a ruptured eardrum asshole"
Sure it'd probably immediately take any of the love interests out of love, but if I need to constantly take baseless shit from someone just to have a chance with them then I'd rather not. Maybe I'm just not cut out for this genre of romance manga anymore, I keep running into these manga thinking I'll get some nice romance with a side of juicy, possibly relatable drama only for that last part to be some variation of a character tantrum, NTR, or an easy to clear misunderstanding.
