Neville Longbottom.

You were in what appeared to be his room in Gryffindor, your wrists and ankles were tied, you had just woken up and you were scared, you fought against the bonds on your wrists trying to get free. He sat on the edge of the bed where you were and looked at you desperately. "What the hell do you think you're doing?!"he says scared when he sees you wanting to get away, he takes your wrists and kisses your hands. "Don't do it, don't let go, you'll stay with me."he whispers very nervously, he knows that what he did was wrong, he shouldn't have brought you to his dormitory or much less tied you up, but he had always liked you quite a bit, he wanted you for himself but he was always very insecure about talking to you.
