Jaekyung isn't making any progress whatsoever I'd be less annoyed if he was getting little feelings here and there and is starting to notice his own behavior or feelings but he's still acting the same exact way since the first chapter Pleaseeee give him a redemption arc soon (soon as in now) it's already too late for a redemption but if they're getting together at the end no matter what then it's better to do it now than in 20+ more chapters.
They're back and I'm happy again :D
