Reading comments on some sites shows, that there are two camps:
Camp one: Ending is awfully written, rushed, Sasuga ruin all developments and story pulling out this coma shit and almost 9 years time gap, erasing all progress and just doing whatever she wants just bcs she wants this, F logic, F realistic, F readers, F you all.
Even Hina doesn't deserve this marriage out of misery, where they literally talked her to marry him, lmao, WTF, how you even have guts to force this SO hard Sasuga, it's your own child, why do you crippling it with your own hands?!..
Camp two: whos, you just whining bcs your girl didn't win, Hina best girl, suck it losers, if you upvote my comment - you are sucker Rui fanboy, go cry on mommy's shoulder.
I'm glad that at least there are (and here two) more people, who understand, how forced and awfully written this ending is. No matter who was you favorite - this is just crap from all sides.
