The art is really good, but the story and the characters are quite boring.
You are an old guy managing an apartment building.
Each days, you can inspect the apartments (break in) and unlock characters stories, explore the city (Haven't done that, so i don't know what it does), make money (it seems to be completely useless), or sleep.
During the week end, you can have "sex" with the characters you unlocked (by sex, I mean look at a still CG for 10 while reading extremely boring text, you can skip it, you won't miss anything, like 99% of the text in the game), train your endurance or train your observation.
What observation does? Dunno, doesn't seem important.
What money does? Dunno, you seem to need it to sleep, but one day of work is worth 10 nights of sleep, considering the game is 16 weeks long... you don't really need it. (and you only need to sleep once a week).
So, just train your endurance until you reach 20 (7 days a week, 1 to sleep, 2 for sex and training, which don't consume HP, you're left with 4 days of consumption), and spam the exploration and sex interactions.
You don't even need to explore actually, it seems that once you unlock the girls for sex interaction, their story progression outside of sex seems completely pointless, it's just useless chatter, and their corruption isn't even taken into account.
It's just useless linear "I stole my step daughter money", "my step daughter is onto me", "my son's girlfriend is an idiot" with extra filler text. Actually, it's the same for the sex scenes.
