What? You said this is a 3D city tour?

Good news, I have traveled through time, and I have a mature, beautiful, and amazingly fit journalist mother at home who likes to wear black stockings.There is a model sister with a thin waist, long legs, delicate face, 36D, and who likes to wear black stockings.There is a lively, cute, youthful and beautiful sister who likes to wear sailor suits and white stockings and is very clingy.There is a coquettish and charming teacher aunt who likes to tease herself and wears amazing black stockings.Moreover, before his death, his father left him a set of magical secrets, which could be used to check the feelings of girls with whom he had a relationship, their current locations, as well as some very "interesting" abilities.Does this kind of opening sound familiar?Yes, the bad news is that the world he lives in seems to be a world where you can easily become green in the city.Fortunately, as a time traveler, he also has a system plug-in that is very popular on the street, so, I will - turn everything around!(Not a fanfiction, because many heroines in this type of game have a bad start, such as the famous "A Certain Nest", so as not to let anyone down, I will not make a fanfiction, but just borrow a setting)
