My Uncle (Harucoi)

At some point, the gaze of his nephew, whom he had always thought was young, began to feel strange. In his dream, Seok-In became sexually aware of his nephew for the first time when Han touched him. However, Seok-In pretended not to notice Han's gaze because he did not want to lose his only family...

"Uncle, you brought this on yourself."

That is how his relationship with his nephew began to go wrong.
