Other Request I'm looking for a novel where the Mc childhood friend betrayed him.

The novel I'm looking for is like Ryuu Kusari no Ori -Kokoro no Uchi no “Kokoro”, and zero attack power swordman, where the Mc childhood friend (lover) abandoned him and later regret it

PS: I'm just new so I think I got prefix wrong.

Edit: I'm not a fan of CN & KR novels and am wondering if there is a jp novel like this, but I will try the CN & KR you recommend.

 

Bruuh literally half of CN novel out there with same plotline

 

True.... Might I recommend "Martial World"
It's completed and full of linmaniacs

 

Yeah Coiling Dragon was the first novel in my mind when I read this thread.

 

I'm not really into CN & KR novels so I haven't checked those novel out

I will check this one out ☺️

I'm not really into Martial art and more towards fantasy type but I will look this one out thx.
