Houses When They Have A Crush
Gryffindor: May be considered the 'brave' house, but they just try to hint at their feelings with words or actions and hope the other person figures it out. Or they're the reason the whole 'they tease you because they like you' thing started.
Hufflepuff: Lingerers af. If they see their crush anywhere, they will find some excuse to stay at that place and just pass back and forth, hoping for a wave or something.
Ravenclaw: Asking questions until they find a similar interest to fangirl/boy over. Then hoping their crush feels the same 'passion' and maybe find their excitement cute.
Slytherin: Accidentally remembering little details. Sometimes, they'll file it away so they can bring it up casually in future conversations like "wait, you love this too?"
