Su Wan, a directionally challenged little painter in the oil painting department, accidentally splashes Lu Shiyan, the aloof top student from computer science, with orange juice on the first day of school, and an unexpected romance begins.
He may seem taciturn, but he crouches down to feed stray cats, stays up late to help her adjust the projection for her art exhibition, and uses code to create a confession featuring an animated cat. She takes her studies seriously, but also clears his name when rumors spread that he cheated to secure a postgraduate recommendation, and paints his profile and the way he holds an umbrella for her.
From sharing library seats and working together on campus projects, to a drone proposal during graduation season, then opening an art studio after marriage, publishing the picture book My Icy Boyfriend, and welcoming their daughter Lu Nianwan, there’s no melodrama, just two people devoted to each other. When the evening breeze meets the blazing sun, a lifetime of clear skies begins.
