Its such a shame that such a great story is ending in such a distasteful manner. Up to that point I really loved that story but this last chapter basically nearly throws me into a depression, frankly to me its obvious the Dev decided to hastily conclude the story. Now the reason I am saying this is because mostly the game crisis came one at a time and typically went thru a pretty typical pattern of high - low - high, basically things were going great, a crisis appear that caused things to go low, than as the crisis is solved it went back up high, its a typical pattern for anything short of Drama or Horror. The problem here is in this last chapter three different crisis that should have effectively had their own arc all happened back to back.
First the parents return, that should have been like the Aunt Hailey's Arc a crisis taking several chapters that involved the characters trying to hide from the parents that they are in a relationship while still being actively in a relationship, it could have been solved by having them start spending more time at Aunt Hailey's house, continuing to further insert her into the group as another of the contenders for the MC, now some time skip could have happened.
Now as the situation passed over and the characters normalized this new pattern the next crisis could have appeared, the parents announcing they were going to bail out on the kids, at this point the MC & Alice being caught by surprise and shocked, at which point the two plus the others could have discussed the situation and possibly grown closer in the process of finding a solution, either the MC & Alice could have moved to Aunt Hailey's house with her, rather than leave her alone in that house, or the two could have moved together in an Apartment, possibly along with Leah & Melody, possibly Karina too. Either way the situation would have been moved on fluidly to normalize again rather than be turned into a crappy mess as in the last chapter.
Now the next time skip could have happened, you learn that the Dad & Brit broke up, Brit could have blamed the father for the fact her close relationship to her daughter took a serious hit, so it would have soured their relationship and led to them breaking up. At which point now the MC start to consider his future, now one of the connection between Alice and him is broken, namely the familial one, he start to think about his own future and doubt the sustainability of his relationship with his girlfriends, which would lead to him processing along with the help of the girls, ultimately leading to him making a choice between either of the girls, all of them or breaking up with all of them and the conclusion of the story.
This is what should have happened, taking the three crisis of the last chapter and giving each their own arc to solve said crisis, with the final crisis leading to the epilogues based on whom he decided to stay or beak up from. It would have been far less depressing than hammering the crisis and giving no respite or solution to any of them that really feel fluidly involved in the story. Doing things that way would have likely lead to a far more appreciable conclusion rather than this heavy handed chapter that just drive most readers into suffering a depressing time.
