I'm not sure if the rest of this got taken down or if they only uploaded these 3 chapters because they were the most palatable, but hearing that the "is she into the father or daughter" question lasts until the end, I can imagine...
Also not really sure why something like this is a comedy though, unless it is because the author is laughing at the readers' suffering?
if anyone else is wondering how it ends, i found the site where it's published where you can read chapters for free if you sign up (https://yanmaga.jp/comics/蓼食う君も好き好き) and google lens'd the last chapter. which is a really bad substitute for an actual translation but i was desperate. specifically because i wanted to know if all the 1 star reviews knew something i didn't or if they just thought the dad ntr angle was too weird (fair). summary:
in a previous chapter hiro saw karin and her dad at the mall together and she's wondering what they were doing. they all go camping alongside a few other characters. eventually it's night and karin asks who it is that hiro likes (she overheard a conversation earlier). hiro says she likes karin, karin responds something like "i'm sorry, but i'll need time to give you a response... i didn't expect you'd be so bold." i'm doing some interpretation with what google lens gave me here so it's likely i've misinterpreted something and i have no idea if what she says implies she liked hiro all along or not. hiro is shocked by this response, i assume because it implies she has a chance. she wakes up to everyone celebrating her birthday (it's her birthday and she forgot) and it turns out karin and hiro's dad were at the mall because they were buying her a birthday gift: a not-nintendo switch with not-monster hunter. karin looks away from hiro with a flustered expression. END COMIC
so tl;dr: karin probably wasn't into hiro's dad. probably. i don't know what's up with the dreams. there's a couple other chapters up on dynasty scans, but the last upload was nearly a year ago so i doubt it's still being translated. i encourage anyone with actual japanese experience to pick up the translation. i've enjoyed what i've read of this and the author's other comics. probably check if sappho scans has actually dropped it first, for scanlator etiquette reasons. and again, this is a bad interpretation of a poor machine translation that you can verify with the link at the top of the post. i figured out how to make an account and access one of my daily free chapters, you probably can too
