- At the same time, Minjae was called in sick that day.
* Note: The reason why Jinwoo didn't show up and Minjae became absent was because Jinwoo accidentally marked Minjae that day and Minjae took a neutralizer to remove the marking effect.
- Colton thought that the timing of everything that happened was too strange to just be a mere coincidence that the man that he saw talking to Minjae and Damon isn't the same person. Upon seeing Jinwoo's face clearly and hearing his voice, Colton is finally certain that Jinwoo and Damon are the same person. Hence, it is also why he asked Jinwoo upon meeting him in person in Chapter 1, "What exactly did you do to my employee?", referring to Minjae calling in sick that day.
I hope this helps you even a little bit :)
