Any male lead like this?

I want a male lead who is nice only to the female lead but not other girls. She should be special for him. Like he doesn't care for other girls but he would do anything for her. Also, he should be the first one to fall in love. My english is bad, that's why I couldn't explain properly but I hope you understand.  So do you know any romance chinese, korean or taiwanese drama with a male like this?

Love Game in Eastern Fantasy - He's exactly like this,he hates litteraly everyone (not just girls, but has no interest in girls, except his sister), he's planning on never falling in love and that'swhy  seeing him fall in love is so cute! Once he falls for her, he falls hard !
