To know what Ayeon did, you need context on Soyeon (crazy woman):
- Yandere, obsessed with Yuri (red hair guy).
- Yuri wanted to expose Jaerim (the "ugly" black haired guy) as gay and destroy Yuri and Jaerim's relationship so Yuri would finally pay attention to her and would love her (I think that was her thought process; she's pretty dumb)
- an antagonist of the main story, bullied Jaerim for months
- the reason why manhwa is named incorrigible probably
Ayeon
- Soyeon's lackey/bodyguard
- Was in love with Soyeon to the point he would do anything for her. anything.
- Soyeon's plan: Ayeon manipulates Jaerim into falling in love with him and gets Jaerim into coming to the storage room in their high school. Then, Soyeon and her friends record Ayeon raping Jaerim and share the footage to everyone as proof Jaerim is gay (shock)
- It's clear Ayeon didn't want to do any of this, though
- Yuri arrives to save the day (after some complications), and Ayeon smashes the camera
- The last time we see Ayeon in the main story, he's running away from the crime scene, carrying Soyeon, who was knocked unconscious by Yuri.
I read the main story a long time ago and I don't remember what Ayeon did in it.
