Relation

go-between, relationship

Mnemonic

Butler Alfred can read every relation between the staff inside the manor. He knows who's friendly, who's feuding. When tensions flare inside those halls, Alfred steps between both parties as a calm mediator, gently restoring good relations one conversation at a time.
Additional thoughts
Picture Alfred standing in the middle of a grand hallway, palms raised between two arguing servants. The 'inside' radical (中) literally means 'middle'—Alfred is always in the middle of every relationship, mediating. Person + middle = the bond between people.
Quick recall
Butler Alfred mediates every relation inside the manor.
