Your person is still alive
When he returns to the human world, four years have passed. His body is still ten years old. His mind doesn't belong to a ten-year-old boy though. He has seen and felt too much. Nothing can bring back the innocence that he lost.
Being an immortal, he can change his body and take the form he wants.
Choi Minho sighs when he looks at the house that he left years ago. Oh Soo-Mi… she must have left, right?
He enters the house. After crossing the unusually clean courtyard, he opens the door. His foot pauses in the air when he sees the person inside.
"Why," He asks her, "are you here, Noona?"
She raises her head and gives him a bright smile. "Didn't I tell you to call me sister-in-law?"
Her eyes are gone. Choi Minho is filled with shame. He can't enter the house. She should have left. "Why do you want to waste your life on someone who had never deserved you?"
