Hello everyone 😀
I finished reading '' Let Dai '' and it was amazing!

Is there any more manga/manhwa
where the main character in the beginning,
is exposed of hits/kicks/knocks down by the ''bad boy''
who he's later gonna have a relationship with?

and has more than 20 chapters? 🙂

I've already read Totally Captivated & Finder

Hullo!

Well, let's see... The only story which meets both of your criteria is A Night of a Thousand Dreams . It's a 11 volume long manhwa, and it's really good, one of my favourites. 🙂 Based on Arabian Nights, the sultan is pretty abusive at the beginning. He chaines uke and puts him into a cell, then whips, and later forces him in bed, too. (Not sure about the later, but it's hinted) The romance builds up slowly. Really, you should read it^^

There's also Deep Bloody Night, but it's just a oneshot. (manhwa) Starts with some whipping/kicking, which later leads into hate-sex. And it's a vampire story.

Maybe you'd also like Sono Kuchibiru ni Yoru no Tsuyu. I'm nost sure, though, since it's not physical abuse, but rape, and it's a single volume. In Black Sun Doreiou, bad guy puts uke to shame in front of his men, and this manga contains the hottest whipping I've ever read (not with the main couple, though). But then again, it's not kicking/hitting.

Hmm, frankly, I've read so much manga that I can't keep all of them in mind. If I remember some further titles meeting your requests, I'll let you know. 🙂
