i don’t understand anything that’s going on the plot is so weird for me

I don't know which part you're talking about but the sister and their household, Adam's family that's been happening will be explained on the next chapter which is chp 15. They're only following the story of the game. The FL is just trying to find a better ending route for the main character of the story which is the guy in the prison tower. Just think of it as a game with no skip button for the main story but you can do whatever you want and gather some side quests but it has effect.
the black haired dude is an actual doormat and the brunette is annoying af there’s no chemistry between them literally none how did they even fall for each other in the first place? the black haired dude went from disliking him to all of a sudden liking him raw dogging him every sec and he can never say no the brown haired dude which makes me mad cause i wanna see some actual chasing arc or some shit also that geon dude is weird as heck but i love sarang x he’s such a cutie like cmere baby i’ll treat you right that geon did him dirty fr
