Wish this site had spoiler tags..unless I'm just clueless. Let's see if this works.
She tries to set her up with a guy twice her age. She leaves it up to her to decide but says it in such a way that Ai feels pressured to agree even if she just wants to be with Yuzu. lol maybe I made it sound worse but to me that was just rather disgusting. :/
She is not a bitch, or anything. They are related by blood. And in first I thought "They can't be related by blood because author couldn't do something like this" but I was wrong. I had a situation like this in my family too, but I think that a little bit worse. So I know her feelings but as a sister. So please don't tell so rude things about their mother.
[SPOILER ALERT] Umm....this reply is just to clear up the confusion for those who are replying to the Topic master with the assumption that, they are Blood related. Here's the news, they are NOT blood related at all. Everything will be cleared up in the last chapter. But if you want more specifics I can spoil it for you if you want.
Why is the mom such a bitch about them being together? They aren't even related omggggg. (╯°Д °)╯╧╧
