Thanks for resurrecting this one, just binged it, really enjoying it. No complaints about the shota humor, but I also would love a straight adult rom-com version of this without it. The original(?) idea of her being a virgin and her devil price being his virginity (unbeknownst to him) felt like it could carry twice this many chapters before the payoff - and I love a payoff!
So yeah, if this is recycling from another source please let me know. It's a fun angle. Looking forward to where it goes now that such a large part of the tension has been released (in more ways than one amirite).
