Lv Yushuo (Zhao Minji), male (the second son of Lv Caiwan, a playboy), is a nominal manager in his father's furniture company, but his head is empty, and he just wants some unrealistic things every day.

Zhou Rose (kim Ji Soo), female (the daughter of Chang Jun, the voice of a TV station), was beautiful, but a little masculine and narcissistic. Since I met Shuo Guang, I have had a very hard love ...
