was the new bottom and the ex lover twins
i’m so sorry, i don’t believe it’s any of this thank you so so much though!
no, the new lover did not know he was a substitute at all
It must be this then cuz seme uses uke as a replacement of his twin bro and he don't even know about it -

I’m not entirely sure if it’s a manga or webtoon, but the plot goes something like… the bottom loves the top and the top uses him as a substitute for someone else… i’m sorry i really can’t remember anything else. if anyone knows anything with this plot, please help <3 (it’s a BL story)
