How does saeyoung feel about who yoosungs dating?? I cant help but think his first thought would be that she is using him (dispite that not being the case) but we know how worried saeyoung always is
Oh, Saeyoung immediately flies into paranoia. On a good day, he struggles with severe anxiety, but when he finds out Saejoong Choi's daughter is pursuing a romantic relationship with one of his (very few) friends? His mind jumps to all the possible worst-case scenarios.
Is she trying to hurt the people close to Saeyoung, to hurt him? Is she using Yoosung as a pawn to get closer to Saeyoung and take him out? Is she trying to get intel from Yoosung? Will she stalk Yoosung's movements both physically and digitally? He knows agents aren't allowed to have liabilities, but this isn't even a threat from the agency. This is the one threat he fears more than anything else, the specter that has haunted his every step from the moment he drew his first breath.
he's so focused on thinking about her as an enemy, as a threat, as a demon never to be trusted... that he doesn't realize until much later that she's also his half-sister.
but how can he consider her family, when she will never know saejoong choi as a monster but only as a doting, successful father?
(of course, he's not actually a good dad and sae-eun has her own trauma to work through, but that's for a later day. she's also 100% innocent and just wants a golden retriever gamer boyfriend)
(under different circumstances, they could be good friends. in an Another Story timeline, they'd probably bond after everything goes down with the Prime Minister. but since my canon--as Ariella--is Saeyoung's route and the Secret Ending, they... don't ever get as close as they could in Another Story.)
