No Cave.

Won-seok, who used to live in a PC room or in a war without doing anything after graduation, starts a delivery part-time job at Jisung's chicken store, which will soon be his brother-in-law at the recommendation of his sister. My sister even buys expensive Gore-Tex jumpers and hopes the gemstones will pull themselves together. Contrary to such sister's expectations and wishes, it is not easy to adapt to a new life. When a small delivery accident occurred, the gemstone scolded by Jisung took off his jumper and went back to his cave-like PC room.
