Shi Ohn asks Hong Suk to give him more time to pay him back. Even though Hong Suk knows that it is not allowed, he gives him one more month. Meanwhile, Soo Ryun gets mad at him as she finds out, and sends him back to Shi Ohn to get a cosigner.

Si On doesn't like the fact Hong Seok is showing up everywhere he goes. When he was about to believe that Hong Seok came to congratulate his birthday, Si On realizes that he's here for the surety contract, putting pressure to sign the contract. A small party between the two continues as they gradually start opening up to each other.

Not knowing who has signed the contract for him as a cosigner, Si On wonders why it is that Hong Seok is being nice to him. On one pretext or another, Hong Seok continues to support him whenever Si On needs someone. Meanwhile, Jung Hoon refers Si On for a part-time job, but something seems off.
