Or I could of mean he held in the meat longer.. --. _
OMG, I didn't even mean it could mean the uncle. That kinda makes sense.
I legit had whiplash cause I was like why is he being nice, why did he hesitate in throwing the picture, why is he all cuddly? like legit.
I then, that that he did not seem to have malice with his mom, and he even forces Bum into the same position as his mom with the skirt, the cleaning, and the cooking. we even see images of his mother side by side with BUm, and we see him comment on bum smelling like his mom. So, I thought ok, maybe he broke and is now projecting the image of his mom on bum.
BUt, you could be right that he's competing with the image of the uncle.
The "I win" in the end could be interpreted in diffrent ways.... Either Sangwoo saying he wins in superiority, or him being all Bum thinks about (instead of his uncle), or maybe even more. Very mysterious...
