She pretends to be rebellious, hangs out in bars, and looks at handsome guys, but he always catches her. What makes her even more devastated is that this rumored living king of hell is actually her baby-fiancé whom she tried every means to escape!

This marriage to save the family business has exploded into a six-person Shura field. When all the members have high IQs, they collectively fall in love with each other. The campus youth drama has just begun!
