Sister of the guy I like being super nice - meaning?

[Anonymous]

His brother has introduced me to her in group settings recently. Him and I are theoretically just friends but there are feelings both ways.

His sister is super nice - likes all my posts, sent me a birthday wish text on my day, etc. just seems weird knowing that I’ve only met her twice.

Could it be that his brother has been talking about me, or am I overthinking? Im just a little confused

I have an older brother and before him and his girlfriend started dating, he had a humongous crush on her, and I knew about it. Whenever he likes someone or needs any help with something, he tells me, and I give him my advice. He could have talked to her about you, and she may want to get to know you better or she might just be a really nice person. They sound like polite people, why overthink and ruin what you have? If her being nice bothers you, just distance yourself from her... but that would be largely unnecessary especially if you're interested in her brother.

Sounds like it yes it's a possibility that she is being nice because of that reason and of course because she likes you as a friend could be

she likes the idea of you being with him so you and she can be friends
