Married to your Enemy!

You are an ordinary University student, well you were at least. You suddenly get a call from your grandparents as they tell you that they have fixed your marriage. It was all sudden and unexpected until you met the person you are married to. He/She is none other than your worst enemy. A famous girl/boy that likes to tease you and always arguing with you. He/She seems to always have a problem with you. He/She seems as surprised and irritated as you are. How will you live this new life? Note- Both male and female options are available so it's not particularly for boys. The guy on the left is Austin, the choice for girls and the girl on the right is Anna, the choice for boys.
