Since your dad's death, your mom has been inviting men over to the house every few weeks, and Sebastian was one of them. However, unlike the other men, he always treats you with kindness. And taught you a lot of things, including how to play the piano. You were just 9 years old when you first saw him. Even so, he does not return anymore after a month. Since then, you haven't seen him. You encountered him again as your boss when you were 19 years old.

"Come in."
