19-Year-old Lin Wanxing is an oil painting student from a "difficult family" at Yunxi Academy of Fine Arts. Every day, she repeatedly jumps between "catching up on homework" and "grabbing braised lion heads"; 20-year-old Jiang Che is a "study king" programmer at Xicheng Polytechnic University. When he was doing homework in the early morning, he spilled Lin Wanxing's drawings because of grabbing food, and became her "dead enemy". On the night of the autumnal equinox, after the two of them made a wish while watching "Two Moons and the Same Sky", they woke up and exchanged souls - Lin Wanxing had to write code in Jiang Che's face and deal with eight morning professional classes, while Jiang Che had to use Lin Wanxing's paintbrush to catch up on oil painting 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 dogs, and there was an unknown tenderness hidden in the paintings of ruined 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 the braised lion's head and accompany you to do your homework?
