definitely the former. in the recent kr raw chapter thumbnail woojoon can be seen meeting with said friend and tbh if he's coming up multiple times and the author is purposely blurring his eyes im betting he's gonna be relevant to the storyline. i'd like to add that siwon's friend's eyes in season 1 finale were also covered. food for thought!
wait I didn’t realize siwon’s friend’s eyes were also covered! it’s giving side couple crumbs omg i’m so hyped
as much as id love that it'll probably never happen unfortch. both of them are giving irredeemable and esp in siwons friends case, a source of trauma (?)
is woojon’s friend whose eyes are covered supposed to be someone important or is author being mysterious just because? i feel like we haven’t seen him before too like who is this guy
