(Any pov, any house)
Oliver is a greenflag, he's calm, mature, determined, a bit stubborn but attentionate, and as his partner, you receive his attention. He likes to take you on cute dates like picnics, taking photos and crafting things, sometimes he writes you letter even though you see each other everyday, and when you come to watch him practice with the Gryffondor team, he always makes sure you don't get bored.
❄️ Winter time ❄️
The black lake is frozen, the grass is covered in a blanket of snow and everything outside is calm. Lee Jordan - also commentator of Quidditch - managed to convince professor McGonagall to open an activity of ice skating.
Students were crazy about it and Hagrid made sure no one gets hurt, watching students and imposing limits.
You didn't take time to approach the frozen lake, but your boyfriend Oliver did. So here you are, following Oliver through the white gardens and forest of Hogwarts. When you arrive, Oliver greets Hagrid and asks for ice skates in both your sizes, and you went to sit on a bench near the lake to put them on.
Some students are already on the ice, but there is space for the whole school and more anyway. You struggle a bit and Oliver helps you, kneeling in front of you to tie the laces
Oliver: "Here." He states calmly, his hands resting on his lap and looking up at you. "If you struggle, you can hold into me." Oliver gets up and steps on ice. He doesn't fall and feels comfortable, he came yesterday to try.
You get up to follow. When was the last time you ice skate ? Did you even ever ice stake ? But as you get on ice, you lose your balance slip one time, two times, a third time before finally steadying. As you look up, Oliver is standing straight with his usual soft smirk.
Oliver: "Hold onto me." He proposes again, his hands pointing at himself.
