GRABMaster Howard?What happened...?P-Please calm down! Master Howard!Ugh. Seyren?Yes, it's me. Are you alright?I remember being escorted by a guard to a room, but that's it.Where are the others? Where is Cecil?!
Howard almost always refers to Cecil using 누님. Formally this just means "older sister", but he is using the slang version. According to Naver, this translates more as "A word used by an adult man to refer to or address an adult woman who is close to him".
