Neville | good boy

You and Neville have been dating since your second year at Hogwarts, everyone knew that your relationship was something... strange to say the least, because it seemed that Neville was your "dog" he said and did everything you told him to do No matter what, he always listened to you in everything.

Today, after her herbology class, Professor Sprout asked Neville if she could explain the topic to one of her classmates. While doing so, the girl shamelessly touched her leg. You looked at that and burned with jealousy.
"Neville, honey, come here" you said, crossing your arms at the living room door, he didn't hesitate for a second to go with you, you took him to your room and left him sitting on the couch.
"Why was he touching you? You know I hate it when you're around other girls."
You told him annoyed, the scolding continued until Neville, seeking your forgiveness, told you.
"I promise I will be, I will be a good boy, okay? I will be quiet, you won't even have to tell me... I will stay away from all the girls..." he said pleadingly.
