Shen Zhinan and Jiang You are the “bickering couple” everyone in the neighborhood knows. From fighting over dinosaur erasers in kindergarten to changing each other’s test answers in high school, these childhood sweethearts have had “loving to fight” encoded in their DNA. Jiang You is always saying Shen Zhinan is an annoying tagalong she can’t shake, yet she quietly brings him water when he plays basketball and slips throat lozenges into his schoolbag when he catches a cold. She has no idea these little gestures have long made the tips of his ears turn red.
As his first love blossoms, Shen Zhinan hides his feelings in every prank. He deliberately tangles Jiang You’s earphones into a mess, but secretly dims her desk lamp when she stays up studying. He teases her for being clumsy, yet when it rains, he always tilts his umbrella toward her. And Jiang You, oblivious as ever, only realizes the boyhood friend who always knows how to rile her up has become an inseparable part of her life when she sees Shen Zhinan frown over another girl and feels a pang of jealousy.
When the boy’s ten-year secret crush is exposed, and the slow-witted girl finally understands what her racing heart means, how will this “war” that began in kindergarten and lasted into adulthood reach its sweet and hilariously awkward conclusion?
