The story of Lu Qingyan, a rational legal scholar, and Lin Che, a free-spirited oil painting genius, who went from being incompatible rivals to eventually becoming the only light and destination in each other's lives.
When Lu Qingyan's notebook, which recorded the cold laws, was transformed into a chaotic abstract painting by Lin Che's paint, a tit-for-tat confrontation throughout the entire campus erupted. They are neighbors in the dormitory, opponents with different views in the classroom, and the most unreasonable existences in each other's eyes.
However, an accident forced the two to start a "living together" life. In the friction and collision of being forced to live together, they glimpsed each other's unknown truth: Lu Qingyan discovered the delicacy and kindness under Lin Che's free and easy appearance, while Lin Che came into contact with the loneliness and scars under Lu Qingyan's perfect mask. The high walls built by reason and the sharp spikes erected by sensibility are quietly disintegrating unconsciously.
When the undercurrent of ambiguity surges in the guardianship and companionship, a kiss after the school anniversary party completely ignites the long-suppressed emotions. However, when the love affair is exposed, pressure from family and the world comes like a storm. In the pull between ideals and reality, they must face a choice together: Compromise to the world, or bravely define their future for each other?
This is the collision of order and color, the blend of reason and sensibility. From rivals to soul mates, they used a youthful gamble to prove that love is the only law.
