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.

In order to make Si On practice hard and better prepare for his audition, Hong Seok goes to Si On's part-time job, pretending that he's Si On. The part-time job turns out to be modeling for a photoshoot. And Hong Seok happens to overhear that Si On's rival is coming up with a scheme so that Si On can't win the audition.
