Chapter 20: You can't understand

• Upon reaching the door, Yul's steps slowed down. He took deep breaths and stabilized himself. Then lightly knocked on the door. He waited, but when the door didn't open, he knocked again.
• Some shuffling was heard on the inside and a few seconds later, the door slowly opened to reveal a devastated looking Zeng with red puffy eyes and disheveled hair. Yul felt his heart sink at the sight.
• As soon as he saw Yul on the other side, Zeng tried closing the door but Yul held on with full force and made his way in. In a comparison of brute strength, Yul was way stronger and hence successfully entered the inside of the apartment as Zeng took a few steps back and Yul locked the door behind him, both breathing heavily.
