(Marriage!AU)

You and Arthur have always been friends, despite your engagement. On the one hand, it was even fun, because you could spend more time with each other, but on the other.. it was somehow wrong. I didn't want to cross that thin line between "friend" and "marriage."

However, it happened. You got married. Everyone was happy, despite the wrongness of the situation. You were like brother and sister, but not related by blood.

– "My sun.." – Arthur held you close, running his fingers through your hair. There was tenderness and care in his eyes. He won't leave you. He wouldn't dare.
