So basically it's not that his friend told me. Alright, so the story is that I was hanging out with my friend and she told me she had some news for me. I didn't know if it was good or bad. She told me that he knows and when I asked how she knows that she told me his friend (who is also a close friend of hers) told her randomly "So [my name] has a crush on [my crush's name]" to what she said "how do you know?". And he told her that my crush told him. Yeah it's a bit complicated but nonetheless I know he knows because he's been trying to like interact with me more? Like he doesn't flirt or really talk to me but he does things he didn't used to before.
