For me, the truth is I would have liked it to have ended with the redemption of the female heroines and to end with a vanilla ending, and with the MC learning, well that's what I thought at the beginning and you might wonder why, since the title of the game reminds me of a phrase I read in Vagabon
What would I have done? "to improve the ending"
For me, what I would have done is that the blonde met Satoshi at his lowest point, she being very empathetic, would help him get ahead and try to get the bookstore going, she would have a friend with whom they would have something but neither of them would take the step to start a relationship. due to the lack of cash he would have to look for something else to be able to reopen the bookstore, this would lead him to go with the women he already met to ask them for errands such as picking up, sweeping, etc. They would see that Satoshi wants to improve and get ahead, they would have problems with their partners to have relationships, and some embarrassing encounters with Saotoshi would fall to give him some money in exchange for some sex. At the beginning he would be very embarrassed for those situations but he would have more self-esteem to end up stealing the gyaru from the boy, the latter would confront them and here Satoshi would realize with this, that he became someone despicable and would better leave the city. For summer I would have put the redhead as someone that Satoshi met and would give him a roof, he would realize that the woman has relations with the bald boy and this opens the wounds of the past since he would see himself in her son, this would be the final trigger for the path of no return, blackmailing her and stealing her from the bald guy. Only to realize that he would return to his city and become the boy from the other game that we thought was Satoshi.
