This definitely sounds like Thousand Autumns but idk if there a manhua for it tho
Nop..
Is it a Chinese manhua? If so it might be 'silent lover'...but I guess I might be wrong
It could be Fall In Mistaken Love
It also has a similar plot...
The one I'm looking for might be wuxia
I found the title... its lone swan(dropped)
I dont really remember the story but it goes like the seme is a villain of sort and uke has amnesia or his clan wiped his memory. i really dont know if my version is correct or not :3. And the story was dropped..
