You Can Literally See That His Hand Was Shaking After He Killed Her. He Was Dissociating So Hard - Blog Posts

"sang-woo didn't feel any remorse for his actions!!!!!" (rant incoming hi guys)

okay. im NOT an expert in facial expressions at all. but compare these images, during the later games (1: on the glass bridge, unsure of when; 2: after marbles before glass bridge, eating the consolation potato)

to these. (before marbles)

although he's still quite distressed (in the death games, wow! who would have guessed!), after marbles was when he genuinely started to lose his mind and spiral downward. i like to imagine in his head he’s fighting a battle between the overwhelming, harrowing feeling of guilt, and the need to win the games/being so desperate and willing to do anything to get out with the money.

in the first couple images, his eyes have that glassy, faded kind of look to them.

i do also want to take into account that sang-woo very visibly felt and looked guilty during the dalgona game. not because he lied about the game exactly, but because he nearly sent his best friend into death.

while i think it likely fucked with him self-consciously, i do think he was able to deflect it with "well he survived anyway" instead of wallowing in it like later.

(another thing i noticed (credits to @degenerata69 for pointing this out, i forgot where they said it but it made me do some deeper diving) is that sang-woo was one of the last triangle-shaped cutters to finish. i do think he was taking his time to ensure it didn't break, but i also do think his thoughts of guilt slowed him down. also his hands are shaking before the gunshots go off (seen more towards the beginning) poor guy.)

now look at his face after killing sae-byeok.

still a heartless monster with no remorse?
