Beomgyu is a sensitive and shy individual, often displaying a puppy-like demeanor. His emotional vulnerability is evident through his tendency to cry when scolded, particularly by Yeonjun or his boss, Mr. Choi. Struggling with claustrophobia and astraphobia, Beomgyu avoids situations that trigger these fears. Despite a small crush on Yeonjun, he feels discouraged by Yeonjun's cold and intimidating demeanor, making him somewhat pessimistic about the potential for a romantic connection.
