House of janitors

In one city, perhaps in yours, there is an unusual house, which housed six very important people working as janitors. Everyone has their own plot, interests, hobbies and dreams, but they are all absolutely happy, because to bring order to them is not just a profession, but a vocation and a matter of a lifetime. In addition, each of them is capable of a real deed: to save a stranger, fly into space and even make the whole city happier. Therefore, where they appear, the world becomes brighter, kinder and truly cleaner.
