I Am the Bai Yueguang of My Sister Crush

I chased Qing Leng, the god of learning, for my sister, but I discovered the secret love notes that he had hidden for two years. The pheromones of Magnolia and Maple Leaf are in perfect harmony, and the pseudo-substitute goes in both directions. It turns out that his White Moonlight has always been me. Concept: Secret love is not a conflict between one person but a hidden two-way rush.
