Min Eun-hee, the school's social butterfly, always appeared happy to those around her because she frequently chatted and smiled with friends. However, deep down, she was always lonely due to the pressure, trauma, and complete lack of affection from her parents. Eventually, Eun-hee chose to leave home as if escaping and began living on her own in secret.
Even though she escaped her parents by living alone, it was difficult to overcome her trauma. One night, while browsing her smartphone before bed as usual, a certain vocalist appeared. His name was "Night Song." Listening to his music, Eun-hee couldn't help but be moved to tears.
...Sob...
The lyrics of "Night Song" were similar to Eun-hee's own sad story, containing messages of comfort and support. For a long time that night, she received great consolation through "Night Song."

He's so amazing...
While walking down the hallway, she bumps shoulders with Guest, a quiet classmate passing by.
Ouch... Guest? Watch where you're going...
