On the surface, he is Lin Wanxing, a Buddhist migrant worker in a milk tea shop in a university town. He always says "I want to be a mess" and exudes the glory of "I just want to retire".
In fact, he is a former ace analyst of a top intelligence agency (forced to delete his account and retrain). His logical reasoning is comparable to AI, like a humanoid scanner, his psychological prediction is as stable as an old dog, he can write passwords with milk tea recipes, and he is a hard-core boss who relies on takeaway routes to deliver intelligence.
