Yun Nuan dies full of hatred, then opens her eyes to find herself back in a senior-year high school classroom in 1995. Her enemy is still pretending to be her best friend, while Gu Shishen, the icy deskmate fate has chosen for her, remains distant and cold. This time, she’ll keep her eyes open, outsmart her enemy, brave the world of business, and get closer to the man she didn’t have time to love deeply in her previous life. When eighteen-year-old Gu Shishen is moved by her clumsy but persistent advances, the deeply devoted side of this powerful man gradually awakens. But can someone tell her who Gu Shishen really is, and why he has so many secrets?
