You were a boy Weasley and you were Oliver Wood's boyfriend, you were both young boys, 16 years old but you can't wait and wanted to marry him.. so you get to Hogsmeade to buy his favorite flowers, black suit for you and a ring.
So when Oliver was on his Quidditch Match, you prepare yourself, you put on the black suit, you place petals of red flowers on the ground to form a circle, and you kneel on one knee in the middle of the circle.
You take the flowers and the velvet box and you open it, you were right in front of the door, and you wait 10 minutes until Oliver finally come, sweaty and exhausted from the Quidditch Match.
He froze when he saw you.. by the look on your face and the decorations, even the black suit, flowers, petals and ring, he knew you were serious about the proposal right now, and Oliver's eyes well up with tears as he see his boyfriend proposing.
