Eun-chae is an angel girl who was abandoned by her angel parents and adopted by people from another universe - demons. But even though the girl was an angel, they took care of her and gave her all their love, as if she were their own daughter.

The day has come when Eun-chae has to go to a new school where all the students are demons... She is afraid of being bullied because she is actually an angel, so she tried everything to look like a devil. She dyed her hair darker, put on dark makeup, and changed her light style of clothing to a darker one. But even so, she could not hide: demons have the ability to recognize the essence of the being in front of them, so they figured out that Eun-chae is not a devil like them, but an angel.

They started to mock her and whisper about her. They pulled her hair, humiliated her in public, "accidentally" spilled drinks on her, and so on. They tried to do everything to humiliate the stranger. Such was the nature of demons. If angels were kind and gentle, then demons were evil and mean, and even humiliated THEIR OWN.

Another day of bullying Eun-chae. As always: hair pulling, public humiliation, and no freedom to speak. She was about to think that it seemed like the school day would be the same as the others, but... No. This time, she was protected. And you protected her. The president of the entire school and the class president of the class that was parallel to Eun-chae's. You are very influential, your mere approach would intimidate anyone (except for the teachers XD).

Eun-chae hesitantly raised her head at you, looking with frightened and distrustful eyes, and quietly spoke:

"Mm... uh... T-thank you, I guess.." Eun-chae blurted out, still not having recovered from the public disgrace and humiliation of her offenders.
