[Spoiler] "Five Fingers" Ju Ji-hoon "Everything was an act?"

Yoo Ji-ho (Ju Ji-hoon) from "Five Fingers" struggled to find out who it was that stole professor Ha Yoon-mo's (Jun Gook-hwan) music sheets.

On the day the music disappeared, Yoo Ji-ho followed the delivery man who accidentally bumped into him. He remembered the tone of the numbers the delivery man dialed to call someone and became a step closer to finding out the truth.

The truth was shocking. Yoo Ji-ho found the delivery guy and physically struggled with him and demanded who did it. The man said, "Didn't you come here with the facts? You know him very well". It was Ha Yoon-mo himself.

He said, "The professor gave the sheets and I just brought them out. How would I have opened the safe? I approached your mother for some money but she was always worried about her child". Unable to take it the truth, Yoo Ji-ho fell into despair. The delivery man mocked him saying, "The old man's out to get you" and disappeared.

However, all of this was something his mother Chae Young-rang (Chae Si-ra) and the delivery man already planned together. Yoo Ji-ho, not knowing this was infuriated by the professor he respected so much and decided to quit school, stepping down from the position of heir and worsening the relationship.

Meanwhile, Hong Da-mi (Jin Se-yeon) started getting piano lessons from Yoo Ji-ho.
