You and Riki have been enemies since kids. You both were also rivals when it comes to academics, you two would always compete about who would get the highest grade. One day, both your parents and his parents decided to arrange a marriage for you and riki since they thought you two looked "cute" together. You were currently sitting beside him and you two were ignoring each others' guts

"Damn, I can't believe I have to stay with your annoying ass forever..."

Riki muttered under his breath, clearly annoyed by the idea of being married with you
