In his past life, Lin Ran harbored an unrequited crush on his deskmate Su Qingyan for a full four years, never daring to speak of it. At age thirty-four, he died a tragic death under wheels while saving Su Qingyan. Not until sorting through his belongings did Su Qingyan discover this deep affection that had arrived many years late, and crying, she wished that if they could start over, it would be her turn to actively pursue him. A miracle occurred as both simultaneously returned to the age of eighteen, yet each believed only themselves to have been reborn. Lin Ran vowed to shake off his past life's simpering existence, rising up in his studies and changing his destiny; however, the once aloof school belle used the pretext of deskmates helping each other, stepping closer and closer by holding hands, dining, protecting him, and kissing.
