All that shit on chapter 1 just for it to be a convenient reason for the whole premise to happen
Like why can it not happen way before this manga takes place? From the looks of it, he actually knows what evil eye is and hence he should at least know that the benefit of getting it will outweigh the danger of having him to seal a demon in his body.
But alas I'm here for the erotica tag so story be damned
wait shit i just realized it's the same author for other 3 manga with the same questionable plot. no wonder. well at least this one got something to sell.
