Hey,im5not sure about a type of side story but I just now realized something,Doyeon basically pretended since childhood to be the good girl right so she get get people to like her and because she wanted to be adopted and loved,why the fuck am I now seeing it NOW,that bitch did the same RIZZ to Jinjoo,the Doyeon Jinjoo gave her body to was the good girl persona and so it's the persona that Jinjoo tried to use so she could be and feel safe and have on her side and keep in her life or even posess.
Now Doyeon is showing Jinjoo who she really is and isn't that the same thing her husband did to her,Jinjoo had problems at home and Changyang must have gotten to know her and gained her trust by being that nice older guy who she come go to for anything and he love boomed her and she fell for it and married his dumb ass,Doyeon was that way with Jinjoo too,cooking for her,treating her with extra care,trying to earn her trust especially since she knew Jinjoo didn't trust her and then wanting sex,Jinjoo really does see Doyeon and her husband as one in the same and is why she sees their relationship as a dead end.
Wait you're actually so right...
There's a lot of arguing going on in the comments and this story is getting even darker (who would've thought that was possible) so let's talk about something lighter.
What kinda AU Side Story would you like for Doyeon and Jinjoo? I personally would like either:
fantasy AU (with mermaid Jinjoo and Pirate Doyeon)
An actor AU ('Please Leave My House' is never going to be finished, so I need an au in some way)
Or, because there it's basically non existent in the GL community, an Alpha/Omega Au! Doyeon is the most Alpha, to have ever Alpha and Jinjoo screams ideal Omega but also beautiful Beta.
