Okay, I have seen these dramas :
Boys over flowers (it's versions too)
Secret Garden
1% Of something
5 to 9
Sekai Ichi Muzukashii Koi
They had one thing common except 5 to 9 (loved it still) that the male lead was arrogant , cold , mean , jerk-ish, narcissistic , tsundere ,playboy, overall not-good- guy and with cold personality who doesn't really care for people and girls too but he falls for female lead First . He didn't know how to show care and affection and was being weird and not realizing that he had fallen for her. But He began to change due to female lead and only show his love , care for female lead even tho they were still a bit mean-ish but inside they really love female lead and change due to her. and began a better person at least .BONUS : He can be kind of obsessed with female lead or head over heels for her or jealous.
Female lead were pretty headstrong and stand up for herself , also she really don't give a wuff or interest in him and focus on herself rather than thinking about male lead. i don't mind her liking another guy but i want headstrong female lead who doesn't have interest in male lead and slowly began to like him too. No chasing the guy but instead not showing interest in him.
Sorry for being picky but i realllllly want to see this.
Genre doesn't matter but no sad ending.
you can recommend me from any country ( Taiwan , China , Japanese , South Korea , Thailand , Turkey etc)
Thank you. :D
