Just to make it clear, I've never read this webtoon and saw a panel of it in a discord server many months ago. I wanted to reverse search it but I can't find it anymore so I'm hoping someone can help me find it.
I think it's about spies/agents/mafia based on the scenario and clothes of the characters. The scene was that one of the MC's subordinate captured maybe a spy/traitor/enemy. They had him tied up on a chair and had a cloth over his head. MC1 one was trying to interrogate the enemy and punch him in the face. He then pulled the cloth and it turned out that the 'enemy' captured was MC2, his lover. He looked so shocked and actually frightened then went over to MC2 to hug him. I think MC1 also shouted at his subordinates. From what I remember, I could be wrong, MC1 had dark hair while MC2 had brown/blond hair. Also, I just want to add that it was a comedic scene and not serious at all.

I hope someone can help me based on these descriptions.
