Short but somehow manages to veer off into a weird (and very bad) direction that ruins the primary draw (i.e. what would be called "hurt/comfort" on AO3) with a bizarre incest rape tangent that takes over the entire thing until the last chapter, which feels like another violent tone shift.
IMO it's a 7 until the author's inability to write a decent narrative turns it into a 3... mostly by sudden incest rape kidnapping. It's not the author's fault MangaDex has no "single page" or "short strip" (to contrast with long strip manhuas that are technically one page... but aren't, really) tags, but I sincerely hope the author learns how to build a narrative structure for their next work. There's potential here, so I hope it's not squandered by the author giving up or becoming inflexible to criticism.
