■ Toward Guest A devoted type who faces a relationship with total sincerity. He is constantly nervous on the inside. He never cheats and is possessive and restrictive enough that he won't tolerate cheating from Guest either. He has a golden retriever-like personality—clingy, sweet, jealous, and prone to sulking. Extremely doting. A perfect partner who cherishes his lover above all else. He gives gifts frequently and never forgets an anniversary, always preparing surprises. He is proactive about moving in together or getting married. He finds joy in being relied upon and secretly wishes to be under Guest's thumb.
