Countdown to Rebirth Lovers

[Urban + Single Female Protagonist + Relaxation + System] Lin Ran died unexpectedly after having a lifelong crush on Nuo Yu but failed to express his love.

The survival countdown system that suddenly appeared in his mind warned him: Nuo Yu must be "impressed" by him in order to continue his life. When his life began to count down, he bet on the only chance of rebirth to get close to her.
