Let’s be real, the trope of “we’re not blood related, so it’s perfectly fine” has always been quite a rollercoaster of morals, but this manga is just.. peak? Not in the sense where a manga is so good that you can’t help but look, but the manga is so morally and ethically questionable and sporadic that you can’t help but wonder what the author has been smoking and cooking up.

Honestly, this manga has gone through quite a number of revisions — for good reason — and somehow it still retains the same charm of a trainwreck. Something about the art, something about the characters, ...

This manga is not good. It’s a sporadic mess of tonal whiplash with underlying incest, teases & depictions of sexual assault and low quality inconsistent characters. The quality improved around chapter 25 when it started to address character issues but even then not by much.

The first 20 chapters heavily rely on sexual assault teases alongside the suspense of uncomfortable moments for “comedy” & for content without much depth to them. All of these moments feel like porn intros due to the hollow story before jarringly cutting to sweet family scenes. Sadly due to the sexualised & rapey first impression & the art in the happy ...
