Sana Jung

Sana Jung, who also goes by the pen name Blackskul, is a 15-year-old manga artist, student, and Lee Hoon's next door neighbor.

Appearance
When drawing panels for his manga, he dresses casually, with a white tank top and blue short shorts, and a black glove on his right hand. He wraps a blue towel around his neck when he is done drawing.

During his meeting with his editor, he was wearing a black tank top under a blue-and-white striped long-sleeve with the sleeves rolled up, a black paperboy hat, blue short shorts with thick white hemming, white, knee socks with one green stripe (top) and one yellow stripe (bottom) on the top of the socks, and blue tennis shoes. He also has a black choker on, and a bag that wraps over his shoulder.

In another casual outfit, Sana wears a black leotard that reaches down to his mid-thigh with white short shorts that have black patterning (two stripes on the right and two stars the left), that are laced up on the sides. Over the leotard he has a blue, cropped, off-shoulders, long-sleeved sweater with the same black choker.

Personality
Sana is a very determined boy. Because he grew up hearing words of affirmation, he cannot accept failure. He will work very hard to be in first place, whether that be on Lezhin comics, or in general life. He sets many goals, and will do almost anything to achieve them. Even if that means being mean to his brother or pretending to be friends with people, so be it.

He knows his way around people. He is very two-faced, and is able to decipher what makes people tick. In his persona he shows Hooni, he is a kind, cheerful, innocent boy. He resembles Soorim. In reality, he is cut throat, and goal oriented. Talking about orientation, Parkgee has confirmed Sana is in fact, in love with Soorim.

He is still a very empathetic boy. When he receives an act of kindness from Soorim, he begins to develop feelings for him. He is soft, and a relatively easy egg to crack.

Lee Hoon
Hooni and Sana seemingly have a positive relationship on the outside, but instead Sana is just using him as reference material for his comic. Whenever around him, he puts on a persona of being very interested and impressed with Hooni's obvious lies, and tries to embarrass him when Soorim came over to see his reaction, for more reference material.

Jung Minhyuk
Sana seems constantly fed up with his brother, who is a 27 year-old "Shut in" (in Sana's words). Minhyuk lives with Sana as a gamer, and in their first interaction in the manga (in chapter 30) he gets yelled at for asking for money which he earned at his job down the road, CVS, after spending his own earnings on games, to which Sana says to "You quit your desk job just to become some pro gamer, yet you've done nothing! If you're going to keep being like this, just go back to being a wage slave!" Often Sana calls Minhyuk names when he tries to ask for something, or yells at him.

Jim Oorang
Jim Oorang, also known as "Lemon Fairy" as his online persona, is a person in the same comic editing office as Sana with the comic called "Revenge of the Nerd", and is constantly annoyed by his critique and things said about his own comic. When first critiquing Sana's second comic in chapter 32, he says that Sana is lacking research, the character is very cliché and the MC was too obvious with the lack of detailing. When he was finished speaking, Oorang says "I'm actually a big fan of yours, Blackskul. But this is a bit of a letdown~" and "Well- it can't be helped since you're still so young~ Stuff like this needs some age and experience!" He's constantly critiquing and trying to one-up Sana with his own comic.

Oh Sooho
Oh Sooho is one of Sana's classmates and friends. When he was shown in chapter 42, he is amazed by Sana's new project, saying that the MC looks looks wimpy and depressed, but says, "Oi, if you want an MC design you should just look in the mirror. I think that would come out much cuter?". Sana got pissed and said "I told you not to say that between us guys..", in which Oh apologized. Sana, after the previous statement, asks for him to read a storyboard for his new comic. Oh thinks it's funny, laughing, with Sana being happy and blushing at the compliment on his work. He afterwards asks if there is actually someone like in the comic, to which Sana replied "Ah, well~ There is someone similar."

Trivia
