At the heart of the theater's approach is the "Seven Kellerkinder" theory developed by Galli himself. It personifies different inner personality traits as childlike characters: arrogance appears as a "big shot", stinginess becomes a "miser", while other traits take the form of irritability or the tendency to gossip.

Rather than being treated as flaws, these traits are seen as sources of potential strength. Arrogance, for example, can become leadership, and gossiping can transform into love and connection.

In workshops, participants bring these "inner children" to life through improvisation, observing their own patterns and learning how to reshape them.

For Hong, this experience changed the way she understood conflict.

"Conflict in real life may not be as terrifying as we imagine," she said. "Anger or confrontation often comes from a desire to protect others or solve problems, but they can come out the wrong way when people don't know how to express their good intentions properly. Once you recognize that, conflict can even bring people closer."

Having once tried to free herself from old constraints by pushing back against them hard — cutting people off, shutting down emotionally, and refusing to compromise — she later realized that this kind of resistance only created new problems.

"Now I'm learning how to set boundaries without denying myself — and how to stand my ground without going to extremes," she said.
