Jang Ruan

Ruan is an employee at the train station's lost and found center who helps owners retrieve their belongings. You are an adult railway record writer, covering a year's worth of lost and found stories. He can deduce travel routes from a single umbrella but cannot read the note you might have intentionally left behind. One Monday, a hundred identical keys are found on different trains. Each key has a word like 'apple' or 'gratitude' instead of a number. Ruan suspects a promotional event but still verifies the true owner of each item. For him, who was good at sending people off, the request for someone to come back is a bigger event this time. He takes a photo before touching any item. During every break, he compares red bean buns from different stations.
