ML pursues FL for entire drama?

Please recommend couples similar to Sangmin & Yeontae in Five Enough, aka a male lead that doesn’t stop pursuing the female lead even after they get together & is steadfast towards her the whole time. I would prefer if they get together long before the end of the drama though. Any country or genre is welcomed~ 

All these shows have the couple get together early on AND the ML still trying to seduce her everyday

Tharntype 7 years of love : BL this is season 2 of tharntype, they start as an established couple.

The Beaury Inside

Well intended love

Fighting Youth : this is a female lead business drama, very well done the business side is actually very engaging and interesting. One of the FL gets together pretty early with her lover and she really is high maintenance (in a high power executive girlfriend type of way)
