@FredFriendly said, she takes Igaraishi over the premise of him being just her Childhood friend, and confirms it as well however we all know she likes him for what he is, a lovable puppy like guy which she will never admit because of her personality, but the part that gets us all is when she treats him so lowly compared to other people ESPECIALLY Okumma after what he did to her.
tell me, do you think she will give Igarashi a chance after he slept with Subaru from becoming dead drunk?
no, not at all infact she will bring down the worst a girl can bring over a guy, but incase of Okumma, she will go to him in the middle of the night to let him explain, this is what infuriates us all, the different treatment, and there are real people like this that I have met, both men and women and its mostly these people that end up losing the most because they never care about those who really care about them.
