A person can succeed through their own hard work, but sometimes the course of events can play a part, too.
As a lazy couch potato, Sun Kaiwen has no intention of working hard. But somehow, he seems to be caught up in the course of events.
On his first day after transmigrating to the world of Detective Conan, he runs into an old man who seems to have a rather strange way of thinking.
Because Sun Kaiwen knows that Wednesday comes after Tuesday, the old man leaves him his entire estate.
Sun Kaiwen wonders how he got rich all of a sudden. He's inherited a distillery, but he hasn't noticed that its liquor dealers seem a little unusual.
After inheriting the distillery, he opens a cafe in Beika Town, Tokyo, and starts a new life. The cafe's name sums up his attitude: The Slacking-Off Cafe.
