Trace 1.5

An investigator with the National Investigation Service, Han Sihyun, seeks peaceful coexistence with entities known as "Troubles" rather than eliminating them. He repeatedly suggests research into communication methods to his superiors, but his requests are denied. After another rejection, Sihyun, while intoxicated, captures a "Trouble" and begins unauthorized experiments. Initially, interaction proves difficult, but over time, a connection gradually develops between Sihyun and the captured entity.
