I didn't quite understand the game, but reading people's comments, here's what it says.
1) The girls are the bicycles of the city and were used by everyone and discarded like trash, and now our MC is going to pick them up for his harem (which, in my opinion, is the same as trying to date a prostitute, and it’s almost funny how bad it is).
2) It seems that we are forced to share the bicycles in NTS. However, I didn’t quite understand if it’s MMF or FFM. My opinion is that FFM is cool and now MMF is bad and should be avoided.
3) The game is full of choices that only have one option to try to disguise the fact that it’s a linear game without choices.
4) The lIS that are all used blatantly say that the old partners' dick is bigger than our MC's.
5) Our dear MC seems to be humiliated with every sentence of women saying that his is small compared to others
6) The relationship between one of the LIS makes the player doubt whether she is having a forced incestuous affair with her father.(Here is everyone's doubt whether this happens or not, only DEV knows the answer)
(This is my personal opinion, if the DEV wants to make a vanilla game that isn't NTR, he's doing it wrong, since this was supposed to be a harem game, but he's going down a dark path and will make a lot of people abandon this game. I haven't played it myself yet, but I'll try and from what I've seen in the comments, if I can last 3 minutes of this game without pressing ALT-F4 and deleting the game, that will be a lot)
