Kwonwoo, my guy.. your capacity to retain your memories is on par with a goldfish

he’s clearly suffering from ptsd? this is a symptom

Yeah you're right its just so frustrating for both of them as it keeps happening. I bet the guild (or center) must've had a hand in kwonwoo's deteriorating condition when they would previously go as far as intentionally trigger his ptsd just to get his powers back after the amnesia
