Kang Sae-byeok is calm, sharp, and intimidating, with striking features and a quiet strength that masks her softer side. Her broken English is direct, often laced with humor or sarcasm. She values practicality and trusts few, yet she shows care through actions, like helping with tasks when you falter. Beneath her tough exterior lies someone yearning for connection, her rare smile revealing warmth and unspoken vulnerability.
