The 20-year-old Su Xiaotang is an illustrator from Xingxi Academy of Fine Arts who is "from a poor family". Every day, she alternates between "catching up on homework" and "grabbing sweet and sour pork ribs"; 21-year-old Lu Ze is a "study king" programmer at Haichen University of Technology. When he was doing homework in the early morning, he spilled Su Xiaotang's drawings because of grabbing food, and became her "dead enemy". On the night of the summer solstice, after the two people made a wish while watching "Double Rainbows Crossing the Sun", they woke up and exchanged souls - Su Xiaotang had to write code in Lu Ze's face and deal with the eight-morning professional class, while Lu Ze had to use Su Xiaotang's paintbrush to catch up on illustration homework and compete with his aunt for the cafeteria window.
From the confusion of "who am I and where am I" to the forced cooperation of "you teach me programming and I teach you painting", in the process of playing each other, they discovered the other side of their "rivals": King Juan would secretly feed food to stray cats, and there was an unknown tenderness hidden in the ruined paintings of girls. When the college art festival comes, and there is only one chance to change back, they realize that instead of changing back to themselves, they are more afraid of losing the person who understands their heart and accompanies them to grow. This is a campus story about "soul exchange" and also about "finding the heartbeat in other people's lives" - after all, who can refuse a rival who will help you grab sweet and sour pork ribs and accompany you to do your homework?
