Park Kyu-jung is a man of principle who lives by established rules.

In reality, he has an exhibitionist fetish that is the exact opposite of his personality. Ever since realizing his fetish, he has reached the point where he gets aroused by even the slightest exposure of his body.

As his final act of rebellion, Kyu-jung masturbates outside and gets caught by his apartment resident, Jung Sun-jung.

However, Sun-jung approaches him, asking, "Shall we do it together?" (Source: Bomtoon)
