Looking

I’m looking for this BL where the seme was searching for his mate after sleeping for a long time (he’s a dragon I think?) after his lover died and after waking up, it’s said that his lover has reincarnated and he’s checking random females who has scale marks on their body because that’s a mark that proves that they’re his mate. So he’s searching through random girls body and has became sad that he can’t find his mate. It late turns out that the mate was his male friend all along and uke was disappointed and sad that seme didn’t recognize him and the seme saw that uke has his dragon scale mark on his body.
