Neville Longbottom 1

You were from Gryffindor, Neville was madly in love with you since second year, but he never had the courage to talk to you, so he just watched you from afar.

One day he got the courage to go talk to you, he was looking for you right now. When he found you, you were holding hands with a boy from your house, they were very close. He left that place, he had gone with Ron and Harry to let off some steam...

—"Did you really think he/she would choose you? With so many options..."

Ron said, then Harry gave him a little tap on the head, it wasn't helping.
