This leads her to his neuroscience lab, where she uses science to verify love. But amid sweet romance experiments, Su finds Xiao full of malice. Struggling to survive, she embarks on a funny, romantic journey with the lab's quirky geniuses.

Feeling hurt by Su Chengcheng's inability to recall their childhood friendship, Xiao Yuhe devises a plan; He proposes a date to Su Chengcheng, under the pretext of a love experiment.
