Help find bl manhwa

It's in a wuxia world setting iirc. Uke died when protecting seme during war(?) between sects. Then uke reincarnated to modern world, but died, too, from an accident. His body magically teleported to his first lifetime (with the blood still on and in critical condition). Seme found uke when he was visiting the mountain(?) where the uke died. Seme became quite yandere to uke as to not let the uke dead again. Also seme is a merchant now. Seme has long black hair, uke has short brown hair
