MANEEE forget that main guy with the long hair who is that neighbor

He's this guy >>> https://www.mangago.zone/read-manga/gwanggong_industrial_complex_please_candy/uu/to_chapter-5/pg-15/

Just read it I finished and I was like oh erm .. story is kinda um weirdd but he’s still fine

Ikrrrr? I also read it right after reading 1 to 10. I did not expect the plot twist I just hope he won't show up again in this manhwa. Dude is hella crazy
