He called him by his real name. The "friend" was like some 'fanboy' (for lack of a better term) for the MCs twin brother who's the real Hyeonseo.
oop i wonder if the ml caught onto that
he probably knows but wants him and not the brother who ran away
his family takes him as an idiot but i feel like he’s actually not that dumb so i wouldn’t be shocked if the ml knew the whole time
Exactlyyy
wait did his ‘friend’ just call him the wrong name or am i tripping
