Inherited a Villain Apartment

An ordinary poor college student x suddenly received a huge inheritance one day—— An apartment building located in the city. X thought this was the beginning of a life of sudden wealth, but he didn't expect it to be the beginning of a nightmare of heartbreak. The people living in this apartment building are not ordinary people, but villains from various time and space who have been defeated by the protagonist's halo. The villains have deep grievances and are mentally ill. As the administrator of this villain's apartment, X's job is to eliminate the villain's resentment and allow the villain to reintegrate into society. X: Live with a smile. However, as the only "ordinary person" in the entire apartment building, X fell into deep thought when faced with the villains who were basically not normal people. "Why are there ancient people here!" "Alpha... Is gender?" "Good guy, this guy is no longer human!" After finally accepting all kinds of strange settings, x worked diligently and finally prescribed the right medicine to resolve the villains' grievances. In return, the villains enthusiastically wanted to teach x all their special skills. X:... I don't need it! I'm so grateful that you guys can work hard and don't pay the rent! Villains: Make money? That's not a matter of lifting a finger. Soon after, people discovered that the rising stars in various recent entertainment/financial/military news seemed to all live in the same building. X finally received the rent from the villains in the building. Except for a certain nail household. The one who lives on the top floor, the most powerful villain in legend, the one who all the other villains in the building would close their doors upon hearing his name—— ​x: Mr. S, it's time for you to pay the rent. If you can't hand it over, you can use your body to pay it. S: I guarantee you will be satisfied. X: Wait, I mean to help me manage the apartment, you don't have to do anything...! ! !
