Male lead is head over heels for female lead

I would suggest:The greatest love

I think you will like it,Male lead falls first chases female lead whereas female lead rejected him twice,  I think female lead is his first love as he never felt like that before. I wouldn't say he is cold but he is kinda proud. Give it a try :)

 SSKF:

It has cheating but Jao Sao Rim Tang.

Let me explain the cheating:
He was a big player, using women who offered, only for sex never believing he will fall in love. Then he has to get married for a reason. He is rich and handosme and anyone would marry him but he only wants FL. He cheats a couple times when women throw themselves at him. But weirdly, he always comes back to her and even tells his bed mates, while in bed, that his wife is fascinating and fabulous. Then he wants to sign the marriage certificate with her, to make it legal. He stops cheating after that, when the marriage became real for him and he realised he was learning to love one person.

PLEASE NEVER RECCOMEND THIS DRAMA TO ANYONE EVER EWW

I GOT DIARRHEA BYE-

The legends is amazing for this ...as well as romance is a bonus book ..ancient love poetry ...lady and liar...before we get married....honestly I wish there were more good shows in this genre.

Please keep recommending more dramas like this

I think you would enjoy The Starry Love. Both ML and FL fit your bill. He lives for her and is a complete greenflag. She's rebellious and spunky + speaks her mind. I really love this drama one of the best.

Here's a list I made for head over heels MLs, I note where they chase for a long time while the FL is oblivious: https://mydramalist.com/list/3rkQqyP4
