>And in the true ending she says she wants to marry him, what's your point?
Yeah the brainwashed part of her, and even she says "when she's ready", which means making her own choices.
Kotoyuki was under a spell that made him want to marry Hinako, and it's heavily implied that it ends in sacrifice to the water god.
Kotoyuki is an asshole who comes from an asshole family, but he's not all bad, he's just stooped in tradition.
Hinako doesn't hate Kotoyuki, she hates what he is making her do, what his family wants her to do to appease the water god.
