This project explores the relationship between identity and the concept of the guardian of the archive through a simple yet symbolic performance. The mask, as a vessel of the self-archive, symbolizes the layered identities we construct—both as protection and as a record. The mirror, in contrast, serves as a reflective archive, a resilient keeper of these archives, resisting destruction and revealing only what the mask permits. In the performance, I wear a self-made mask with three forms: fully closed (both doors shut), partially open (one door open), and fully open (both doors open). While wearing the mask, I strike a vintage mirror with a hammer three times. The mirror remains unbroken, and after the third strike, I step out of the darkness.
