Tbh..... I'm less bothered by Wooyeon (who was clinically confirmed to be a psychopath since the beginning---and isn't gonna change), and more annoyed by how spineless In-Seob is...especially with the double standards. You're an adult now! You were nuts enough to follow some guy across the globe to get "revenge" on him, why are you so wishy-washy in all other aspects ( ̄∇ ̄")...???
Like, IDK how to feel about a character that's persistent and persevering but only to be a doormat. At least Wooyeon is just consistently an asshat.
