Wait, i think i have read aja story like this before. Am i wrong? （￣へ￣）

you might not be! there are lots of stories like these. well, following the same idea :D

it’s so similar to peerless alchemist..

most chinese reincarnation follow the same pathline-revenge with killer/cooker/doctor as MC while the ML is someone who's very powerful in the world(to make novel more complicated, they even have a past life(Mc +ml)= fill in plot hole for rebirth)
