Taekbae Watseumnida

Seonho is not a wealthy person, but he is an ordinary courier who lives happily ever after. While delivering deliveries as usual, he happens to meet Jun-goo, who bullied him in high school 10 years ago at the delivery place. Sun-ho was relieved to see Jun-gu, who did not recognize him, but found traces of the murder in his house, and found out that he was a witness. Seon-ho, caught by Jun-goo, runs errands for Jun-goo again as he did 10 years ago... (Source: Naver, translated)
