I was actually gonna say dawn of the dragon on how similar it is not until i read the last part. Is this a manga? I think I've read this one before but that was long ago
Ohh yeah...that one. Where the other male lead was from the underworld and he actually gets together with MC cuz main lead was a jerk!
Main lead had white hair, the other had black hair. And MC is a blondie
I think it was a manhwa or manhua (not sure which one). It's been so long since I read that this was all I could remember. I stopped reading because I got caught up in the latest chapters at the time and ended up forgetting about it. I just randomly remembered it once again a couple of days ago and wanted to read it again and see if the story had ended, but now I don't remember the name to search for it.
I just remember that the family of mc served under this deity/god and that it was tradition to have a female of the family become his bride (if i'm not mistaken). This had been happening throughout many generations of the family and the time had come for the mc's little sister to take on that role. However, the mc stepped in and offered himself up to be her replacement. The two eventually develop fellings for each other, and I also remember that it was revealed that the deity/god was interested only in men (his first partner was a man) and that he did not become sexually involved with the women who were offered to him. I don't even remember if i read this on mangago. Also, I think the description I gave is similar to Dawn of The Dragon, but that't not the one I am looking for.
