Yes , i believe he does in the whole 바닷가, 비치 season he really cared for momo and when aizen (Stabbed) momo he got into rage and episode 293 i think he stabs momo and can't control his anger she he attacks aizen and i believe that he does like and cares about her but on the other hand he does like rangiku matsumoto i suppose well its very hard whos know this is what i think LOL
Well, I personally see it as 더 많이 of a brother/sister relationship, but it could be romantic, 또는 even just a really close friendship. He obviously feels very close to her, and she to him, but there are a lot of reasons why that could be the case.
It’s debatable, like most other Bleach pairings because nothing is ever officially said. He does feel very protective of her and he goes to great lengths to save her, even when she is not in the right frame of mind. So yes there is 사랑 there but like I said it's hard to say whether 또는 not it's romantic 또는 brother/sister love.
I would say that Hitsugaya likes Hinamori because in episode 34, when Hinamori and Kira got arrested for battling, Hitsugaya was alone with 진 Ichimaru. Hitsugaya then warned 진 Ichimaru if he were to hurt Hinamori 또는 let her blood fall, Hitsugaya would kill him. So, in my point of view, Hitsugaya probably likes Hinamori.
