Anissina says she gives him ◐ because his work isn't too troublesome or impressive. I know better.
She finds him interesting and infuriating. She is not used to having a kindred spirit around. He fits into no category of man or beast she has known and she doesn't like it! He needs to be labeled and quantified because as he is it is confusing and that's upsetting. Not that she has any intention of letting him know this! He's just an aberration. It's not like it makes him special or anything.
She likes talking to him. Actually likes doing this which is strange. It's very rare for her to do a lot of sharing her ideas with other people. She didn't always get a lot of positive feedback, so it was easier to just do whatever she was going to do and let people react as they would without worrying much about their opinions.
She feels very competitive with him which is a more comfortable position to take.
His overbearing over his sister reminds her a little of her brother...ish. At least in as much as he is head of the family now and he has some say in her life unfortunately.
He also says strange, embarrassing things sometimes. She hasn't figured out what his angle is on this compliment nonsense of his.
