When my ex-boyfriend fell in love with me

My name is Sunwoo Yeoju. I'm a team leader at a large company. How old am I? I'm 26. I have an ex-boyfriend who I broke up with on bad terms seven years ago. But my intern is my ex-boyfriend? Kim Taehyung, who says he's in love with me and wants to date me again. And Min Yoongi, the company president who's been hovering around me. Who will I choose...?
