Looking for a Korean manhwa I read (plot details included)

Hello, I recently read this story, but I can’t find it anywhere.

It should be around 24 chapters if I remember correctly!
1. Main character is an art student, she works at a PC center (rents out computers) and it’s the day she has to register for classes, she’s working her job the time she has to register for classes so she’s super scattered. She accidentally turns off the wrong PC and the Male lead is unable to register for his classes. She finds this out, and he goes to her university so she’s super freaked out! She ends up going to school and actually ends up in a couple classes with him which makes her super stressed, he was really mad originally, but now he doesn’t care as much so they make up.
They become friends and he starts to develop feelings for her and wants to get closer, the ML is pretty popular and known for being good looking, but it’s nothing insane. The FL has another guy who has a crush on her, he has black hair and is also good looking but she thinks he hates her. In reality they went to after school art classes together and went to the same highschool as him and he developed a crush on her back then.
Recently in the story the ML is working with something he volunteers for outside of school and asks the FL to help him out since part of it includes face painting, she obliges. The girl who runs the club outside of school crushes on the ML, but he doesn’t notice. A child gets lost, and other antics ensue and I don’t really think much has happened since.
If anyone can help me I’d really appreciate it! I know it’s out there and I don’t think it’s super obscure or anything I just can’t find it, it’s fully in color also.
