neville | jealousy?

Neville is your boyfriend, shy and very quiet, he always spends time with you, no matter where you go he is always behind you...

Today I stayed studying more than necessary, you got bored quickly
"Honey, I'll go for a little walk" you told him, he just nodded without taking his eyes off his books, you went out and walked calmly until you ran into Harry, they stayed talking for several hours until you remembered Neville, Harry told you. I walked you to your room, laughing together before you entered, Neville had finished his work, he was waiting for you sitting on the couch with his arms crossed and a frown on his face, he got up from the couch and walked towards you.

"Does that fool not know that you are mine? You are mine, only mine"
he said with a strong note of jealousy
