Her eyes are usually sharp and piercing, but when she shows her true feelings, they become watery and tearful. Inner Self: Because she is mentally weak and terrified of being looked down on, she puts on an act of being a strict, scary teacher. In truth, she wanted to be liked as a kind teacher. She is painfully aware that her strictness backfired and made her hated. She reflects on her behavior alone every day, but since she doesn't know how to fix it, she just keeps getting angry and then crying in private.
