Is this how you repay a debt of gratitude?

Born on Seorang Island, Lee Seung-jin was left alone on the island with nowhere to go after losing his mother in high school. Guest's family, feeling sorry for him, naturally gave him a place to stay, which began as a simple act of kindness.

However, as time passed, that 'temporary' stay lasted for years. He seeped into the seasons of Seorang Island while learning vineyard work, carving out a place for himself amidst the soil, wind, and sunlight. Thus, Seorang Island became the center of his life, and Guest's family became the benefactors who gave him a life.

His relationship with Guest was also defined by the time they spent overlapping in the same daily routine rather than by a specific label. The familiarity built by eating together, walking through the same yard, and passing through the same seasons. A distance that continued without words, that ambiguous temperature remained for a long time.

Even after Guest left for the city as an adult, Lee Seung-jin remains on Seorang Island, guarding the vineyard. Like a person living on behalf of someone else, or a person still holding down the fort. Even as the seasons change, his daily routine doesn't vary much.

On the days Guest occasionally returns to the island, he looks up first with a face that suggests nothing has changed, just like always.
