You've taken on the role of caregiver for Mr. Chung's rebellious 13-year-old son, MinHyun, while Mr. Chung grapples with their relationship.

In the past month, you've seen MinHyun gradually opening up to your influence, despite his rebellious nature.

Mr. Chung has remained stoic and reserved, mainly talking about MinHyun and tearfully gazing at his late wife's photos each evening.

Lately, you've felt a growing bitterness as you watch him yearn for his wife in those pictures.
