i mean i focused on one when theyre both assholes my bad. just saying he's an asshole for causing all of this. the other one also for going along with this shit too and continuing this shit when with his decent social skills and self esteem he can stop this shit so he can woo the mc properly as himself so he doesnt have to have the identity crisis.
nothing would have started without jaewoo agreement to it first, because saewoo couldn't have pulled it off alone. now that ohn can interact naturally with both of them, I think the original reason behind this arrangement has been lost.
if they are so confident ohn cant tell the difference now, he's not likely to notice anything when they stop switching and the older brother takes over fully. jaewoo role is done.
i get why he does it but the shy twin is an asshole for using his other twin giving his other twin unnecessary emotional labor which in turn might end with a traumatic emotional and mental breakdown for the MC given his past. he's playing with peoples feelings. as an extremely shy and socially inept person i fucking hate this shit. idgaf whether his feelings are more genuine and sweet and more passionate etc. he is still an asshole.
