Reverse Puzzle

Lin Zhi, a high school art student, can see the colors of emotions, but Chen Shu, a math genius, lives in an absolute grayscale world. They discovered the "law of memory trading" on campus: if you pawn a memory, you can exchange it for the corresponding talent. For their respective dreams, they began to exchange precious moments related to each other. When Lin Zhi finally gained an absolute sense of lust, and when Chen Shu gained extraordinary thinking, they discovered that the cruelest transaction was not losing love, but that the fact of "having loved" itself was uprooted from memory.
