Have you guys ever had a crush on your best friend? You did? OK then. What about crushing on your best friend who has been in love with her oblivious but heartthrob high school sunbae since forever and the said sunbae happen to be your housemate? No? Never? Well, Lucas can't relate!

She had a crush on him and confess. He likes her, but he can't accept her confession.    

She just got dumped and accidentally sleep with a popular guy in her college.

Everything started with a little white lie Eunji told her mom about Sunggyu and she never expected it would change everything in her life.

In which Lucas accidentally heard Yuqi's talking about him behind his back the night all cast of Keep Running gathered to watch their new season premiere. So what would his reaction be?

Stay away from 'The Princess' everyone said. He has no idea what they're talking about until she tripped over him and make his life a living hell.
