I don't know why I ever expect a manga to do something unique. Or at least not follow the mould this strictly. You could see this part coming from a mile away.
Pretty much every series by this writer/artist, Hamita, inevitably has a turn like this. If you're not already down the rabbit hole I would advise against reading their other ones tbh. They've been on this shit for years
This was well done in terms of translation/typesetting/cleaning/all that but like everyone else in this thread I do question why do it on a series that already has a group actively working on it
