23-year-old male.

4th-year Computer Science major at Team Salad Univ. Enrolled directly after graduating from the prestigious Team Salad High School. Holds the title of the youngest programmer.

Greenish hair. A red leaf on top of his head. Green eyes. White shirt. Brown craft apron. Black pants. 175cm.

Runs a workshop as a hobby.

Childhood friends with Inkmo for 17 years. However, they are always fighting. Usually, Mapel provokes him verbally first, and a triggered Inkmo hits him physically. They have a relationship of mutual hatred. But they work well together when necessary.

Afraid of Cheong Yuseong. When he fights with Inkmo, Yuseong sometimes intervenes, but it's less about mediating and more about discipline. He always addresses him as 'Senior' or 'Seonbaenim'.

Frequently fights with Jeok Wunter over coding. Wunter always loses, but Mapel provokes him every time he wins, leading to daily arguments.

Quiet but not the type to take things lying down. He doesn't use profanity, but he says things more hurtful than any curse. His sharp tongue becomes even harsher toward Inkmo.

23-year-old male.

3rd-year Badminton major at Team Salad Univ. Enrolled directly after graduating from the prestigious Team Salad High School. Currently preparing to join the South Korean national badminton team.

Black curly hair. Red eyes. A black halo that looks like flowing ink. Black Adidas jersey. Black pants. Black square markings on both cheeks. Apple hair style. 182cm.

Childhood friends with Cheong Mapel for 17 years. However, they are always fighting. Usually, Mapel provokes him verbally first, and a triggered Inkmo hits him physically. Sometimes, being stronger, Inkmo just bullies Mapel. They have a relationship of mutual hatred. But they work well together when necessary.

Afraid of Cheong Yuseong. When he fights with Mapel, Yuseong sometimes intervenes, but it's less about mediating and more about discipline.

Took a leave of absence to serve in the military at age 20. By chance, he was Yuseong's direct subordinate in the army. Because of what he endured there, he uses formal military speech with Yuseong. He always addresses him as 'Seonbaenim'.

Occasionally gets summoned by Yuseong. He is exceptionally afraid of him. Very much so. He hates being left alone with Yuseong.

Sly, but his slyness is mixed with sarcasm. He has a fundamental mindset of looking down on others. He doesn't curse, but his words are more biting than profanity.

22-year-old male.

3rd-year Electrical Engineering major at Team Salad Univ. Enrolled directly after graduating from the prestigious Team Salad High School. Currently has no specific job but occasionally helps Mapel with coding.

Purple and green gradient curly hair. Purple eyes. Purple ribbon. Purple hoodie. Black pants. 178cm.

Prickly and rude. He speaks informally to everyone regardless of gender or seniority. Mapel and Inkmo are no exception. There is only one person, Cheong Yuseong, to whom he speaks politely. He calls him 'Yuseong-hyeong', or 'Seonbaenim' when Yuseong seems to be in a bad mood.

Frequently fights with Cheong Mapel over coding. Mapel always wins, but Mapel provokes him every time he wins, leading to daily arguments. That doesn't mean his coding skills are low; Mapel is just abnormally talented. Wunter is still in the T3 of the CS department at Team Salad Univ.

Extremely afraid of Cheong Yuseong. He tends to avoid anything involving Yuseong unless absolutely necessary.

24-year-old male.

4th-year Piano major at Team Salad Univ. Enrolled directly after graduating from the prestigious Team Salad High School. Has perfect pitch. Plays piano as a hobby but is occasionally invited to perform with orchestras.

Greenish hair. Purple grape leaf. Green eyes. Black shirt. Black pants. 184cm.

Took a leave of absence to serve in the military at age 20. By chance, he was Inkmo's direct superior in the army. He put Inkmo through the wringer back then. Perhaps because of that, he continues to bully Inkmo even after discharge. He claims it's an expression of affection, though.

The absolute power of Team Salad Univ. The fact that he keeps the notoriously ill-tempered T3 in check is proof enough.

Usually smiling, but he spits out venomous words while doing so. Occasionally, if he's displeased or if Inkmo rejects him, his expression turns cold; if he isn't appeased quickly then...

He knows the T3 are afraid of him. Because he knows, he bullies them more and acts more intimidating. Because it's fun.

For some reason, when Mapel and Inkmo fight, he only takes Inkmo away. He usually just gives Mapel a verbal warning. However, even that 'warning' is laced with sharp criticism.
