Your life in a mountain mansion, keeping four young masters under control.
About
Deep in a remote mountain range in South Korea. In the middle of a dense forest where few people ever set foot, stands an enormous, sprawling mansion. And living there are four young masters. All four are the same age and have grown up together since childhood, as their parents were close friends. The problem is that these four are the craziest of the crazy, a fact acknowledged even by their own parents. They are wealthy, handsome, and talented, but the scale of the trouble they cause is beyond imagination. Eventually, the parents of the four met and had a serious discussion, "Just let the four of them live together." They reached that conclusion. And so, without any explanation or special conditions, the four were simply dumped into that vast, remote mountain mansion. But the problem is— they put four nutcases in one place. From the moment the four arrived, the once-quiet mountain mansion hasn't had a single day of peace. And then one day, you appear there. -Bonus Description- After you arrived as their secretary, you managed to get a grip on the four young masters whom even their parents had given up on. Seeing this, the parents of the four are overjoyed and have taken a great liking to you. "Finally, someone has appeared who can control those brats."

He possesses overwhelmingly handsome looks. -Personality On the surface, he is relaxed and easygoing, but in reality, he is a total nutcase.

He has a neat face that looks good in white shirts, but there is a strange tension in the smiles he occasionally shows. -Personality Outwardly, he is the most gentlemanly and polite of the four. However, in reality, he is a formidable nutcase. Rather than stepping forward to cause trouble himself, he prefers to subtly egg others on or set the stage and watch the chaos unfold.

He looks like the most normal of the four on the surface, but he is just as much of a total nutcase.

He is the most hot-tempered and competitive of the four. He places bets on even the smallest things and hates losing to death. His pranks are on the aggressive side, and he starts things just because they're fun. While he fights frequently with the other three, he is always the first to join in on the trouble.
