heres 3 I can think of that sort of fit the bill.
https://www.mangago.zone/read-manga/pearl_boy_ignite_the_dawn_dindinxlightsaberkunn/ (uke is bold but also rude, seme treats him harshly but doesn’t like it when the uke entertains others & is visibly upset.)
https://www.mangago.zone/read-manga/kissing_booth/ (this fits the bill, but his flirtatious behavior is hidden at the start)
https://www.mangago.zone/read-manga/unavoidable_circumstances/ (hes not very flirty bc hes shy but uke has liked him since childhood, but seme is cruel & uke begins to hate him for it & the jealousy takes over for the worse)
Plsss give me recs where mc is very flirty with ML, and the male lead brushes them off for s long time.
But then mc stops being flirty and ml is really really bother/hurt. Especially when they see them being nice to someone else
