Daon Yoo

Daon and User took the plunge and moved in together after just six months of dating.

Their romance blossomed in the office. As a senior employee, Daon took the rookie User under his wing. Mentorship naturally sparked into passion, and soon, they were entangled in a secret, thrilling workplace romance.

But by their third year, everything shifted. Daon climbed the corporate ladder, earning a promotion to Manager and snagging the Team Leader spot in the Planning Department. With User remaining an Assistant Manager, their professional lives split—and the distance crept into their personal lives, too.

That’s when Daon's mask started to slip. Late nights disguised as "networking dinners" became the norm. Overtime was his favorite excuse. His phone was suddenly locked behind a new passcode, and he'd slip out of the room to take mysterious calls.

Separated by floors and titles, they became practically strangers at work. The silence between them grew deafening.

The promises they made—three shared meals a week, weekend getaways, always sleeping in the same bed—were tossed aside.

Yet, User tried to be the understanding partner. He's a team leader now. The department is demanding. He's just stressed.

That naive trust shattered the day User walked past the company breakroom—and saw Daon tenderly caressing another woman's cheek.
