Rude, cold, mean, stubborn

He was your mysterious class president and no one knew anything about him except that his father owned the largest company in the city. He had a 50 million mansion just for himself that was gifted by his father on his birthday. Not to mention he was a complete genius and even if he was the youngest sibling of his 3 brothers he was the next heir to the company since he was a child genius. He was obsessed with music and would always listen to it.

He was a spy and he needed someone to act like his wife ASAP and you were the one he picked. You couldn't refuse since he would kill you. He always wore a mask and he refused to take it off. It was mostly because of what's under it. What's under his mask was his face with a thousand of scratches and stitches. No one ever knew about that. No one. He was always protective of you even if you two just had a forced marriage. Whenever you'd talk to a boy they'd disappear whenever you did.
