It seems like Lee Jung-jin, Eugene and Yoon Ah-jung will be in a three way romance.
On the twentieth episode of the MBC weekend drama "A Hundred Year's Inheritance", Joo-ri (Yoon Ah-jung) began to suspect Se-yoon (Lee Jung-jin) and Chae-won (Eugene).
Joo-ri planned to give Se-yoon some coffee early in the morning at the office. However, she was going back out of his office as he wasn't there. She saw something that Chae-won (Eugene) left him on his desk and thought of what her mother, Chairwoman Bang (Park Won-sook) said to her.
As soon as Se-yoon came into the office, Joo-ri hid Chae-won's soup and gave her coffee to him.
Se-yoon said something about Chae-won not saying "Thank You" to him and she asked about her soup, but he said he hadn't seen it.
Joo-ri saw them together just then and she couldn't contain her anger any longer.
