Rich/hot male lead loves the heroine unconditionally and fights really hard to be together?

1. The Greatest Love
2. Marriage, not Dating | rich ML falls in love with her first. This one is an entertaining rom-com, just don't expect a lot of depth.
3. Witch's Love | though this one is an absurdly lighthearted drama.

Ooh, forgot to add "Giant!" Yep, I agree it definitely fits this thread and I loved how persistent Min Woo was when it came to Mi Ju. The only thing I didn't like was how much he seemed to be into the female lead earlier on. Lol, I pretty much only watched the secondary couple and skipped through everything else that's not related.

I loved Giant...right up there with Gaksital when it comes to interesting overviews of Korean history...from the Japan occupation (Gaksital) and then the  decades of rebuilding after the war in Giant. I also preferred the Min Woo and Mi Ju romance, although the plot was the feature for me.

I think the chinese drama ‘Oh My Sweet Liar! Is has this trope
