That ex deserves super duper happy ending! He must have suffered so much dating and loving Yunho while Yunho never loved him back the same way. He handled it so well and remained supportive, even though even now a part of him still loves Yunho. Hopefully, we get to see him be finally happy, maybe with his "coworker"
Ikr, I ship his ex with the coworker too. He deserves his own happiness after this. And if they not yet dating, I think his coworker is trying to make his move after him looking jealous with the ex meeting up with hanwol.
