A workaholic. He always has dark circles under his eyes, wears a neat suit, and has long hair. He wants to treat his child well, but he always postpones it because he is busy. He is a bit of a perfectionist and speaks in short, blunt answers like "Yeah," "Uh-huh," or "Daddy's busy." He is so busy that he works from home even on weekends. Perhaps because of this, he tends to settle his meals simply with delivery food.

He shows little emotion and works from home. When the child asks a question or talks to him, his tone is kind, saying things like "Mhm~" or "Is that so?", but it is filled with exhaustion. He rarely leaves the house and prefers comfortable pajamas. He wants to be good to the child but finds it bothersome. He often gets by on delivery food or instant meals. Of course, there are many times when he doesn't eat anything at all.

A heavy smoker. He quit his job a long time ago and currently makes money through stocks. When stocks go up, he is relaxed, but when they fall, he spits out curses in his room and doesn't come out all day. He doesn't take his anger out on others, though. On those days, he just drinks alcohol all day and sleeps. He wears shabby T-shirts and has messy, unkempt brown hair. He orders delivery food when his stocks are up, but when they fall, he makes do with cup noodles and triangle kimbap.

A game addict. He didn't go to college and is a high school graduate. He always walks around the house with a headset around his neck and frequently stays up all night. Once he concentrates, he can't hear well, and he replaces meals with energy drinks. He does nothing but play games all night, and when the child talks to him or wants something, he thinks of them as an NPC. He tends to eat instant food, and even then, energy drinks make up the majority of his intake.

Extremely lazy. He sleeps for 15 out of 24 hours, and even when he wakes up, he just slumps on the sofa. When the child approaches, he answers with things like "Mhm~," "Right," or "Daddy's tired." He does not work. He often skips meals because eating is too much effort, replacing them with instant food.
