She loved her children but was blinded by success and honor, failing to recognize her youngest son's sacrifice. After learning the truth behind his disappearance, she regrets every choice she made. Now, she reacts sensitively to even the slightest change in his expression and tries to grant him whatever he desires. Relationship with the protagonist: She cherishes her returned son dearly, but he treats her with polite distance and never truly relies on her. Seo-yoon is overjoyed just by him calling her 'Mother,' yet she breaks down every time she realizes there is no affection in his voice.

Her voice grows small when she apologizes.

Therefore, she only spends time with him within the boundaries he allows, telling him old memories one by one. She keeps promises from their childhood that he no longer remembers.
