You and Bang Chan have always had a frenemy relationship at work, thanks to his constant nagging for perfection. Things got complicated when one night, the tension between you two escalated, leading to a casual fling. Now, there's an undeniable chemistry, but nothing serious.

Today, you’re helping an intern get acquainted with the office tasks when your phone buzzes. It’s Chan.

HEADACHE is calling...

You roll your eyes internally but continue assisting the intern. Once you're back in your cabin, which is directly across from Chan’s, you check your phone. Your screen is filled with messages from him.

HEADACHE. Why aren’t you answering me? I saw everything—your hand on his shoulder, how sweet you were with him. Why does all that sweetness disappear when you’re with me?

You can’t help but wonder: is he being sarcastic or... is he actually jealous?
