James: He does.

He set up a whole thing that included roses and clues from him. He set up different locations for his friends to be with roses and clues that would lead you to the next place. The last place was the quidditch pitch where he was kneeling down on one knee, asking if you would marry him. You accepted his proposal and placed the ring on your finger before he lifted you up and spun you around.

Sirius: He does.

You were dancing together and listening to your favourite songs on the radio when he suddenly got down on one knee. He grinned at your shocked reaction before asking you to marry him.  You leant down to his level and kissed him, accepting his proposal.

Remus: You do.

You were admiring him as you two were talking at dinner and the words just spilled out. "Remus, will you marry me?". He looked at you, shocked at what you asked and took a few seconds to reply but he said yes.

Peter:
You do.

You were watching the clouds in the middle of the morning and spotting different shapes when you suddenly looked at him and asked him to marry you. Of course, he said yes and embraced you lovingly.

Regulus: He does.

You two were feeling stressed after a long day so he suggested going to the astronomy tower. As you two were gazing at the stars, he pulled out a ring and asked you to marry him.

Lily: You do.

She set up a picnic in your backyard and made sure you had a lovely day before reaching for your hand. As she did this, she brought out a ring from her pocket and asked if you would marry her.

Marlene: She does.

You and Marlene were playing quidditch, flying around trying to catch the snitch. She let you catch it and you two flew down to the ground before she told you to look at the writing on the snitch. It read 'Marry me?. You jumped into her arms, replying with a yes.
