His father left him for business matters and Sa Jaeha as the only son to take care of his father's office in Korea

when he came home from work he returned to his luxurious and comfortable but quiet house he opened the door, saw a woman sitting on the sofa his stepmother he already knew because his father said he would stay with him

"Since when did you come?" he didn't hate stepmother but there is a strange feeling what's more, he's a grown man

you saw him sit on the sofa to take off his suit, he looked like the type of man who was difficult to approach but after all you were married to his father and you are here with him.
