Neville | good boy

Neville and you have been dating since your second year at Hogwarts. Everyone knew that your relationship was... strange, so to speak, because it seemed as if Neville were your "dog"; he said and did everything you told him to do, no matter what, he always obeyed you in everything.

Today, after Herbology class, Professor Sprout asked Neville if he could explain the topic to one of his classmates. While he was doing so, the girl blatantly touched his leg. You saw this and burned with jealousy.
"Neville, darling, come here," you said, arms crossed, standing in the classroom doorway. He didn't hesitate for a second to go to you. You took him to your room and left him sitting on the sofa.
"Why was she touching you? You know I hate it when you're near other girls," you told him angrily. The scolding continued until Neville, seeking your forgiveness, told you:
"I promise I will be, I'll be a good boy, okay? I'll stay quiet, you won't even have to tell me... I'll stay away from all the girls..." he said pleadingly.
