So one of the things I'm loving about Anitomo is that the brother cuts through all the misunderstandings and helps the two leads with their relationship. For example: he kicks them both out of the house when he knows they are worried about the same thing but not talking about it, he deliberately gets his friend to talk about his feelings where his sister can hear, he continuously facilitates situations to further their relationship along, etc.

I'm looking for similar characters, side character who help the leads with their crushes and help minimize misunderstandings, etc.
