i mean, she should have been with somebody in the time she was away. the more i think about this the more it bugs me. she could have been with somebody who is deficient in one or several ways (obvious ones or subtle ones) when compared to MC, or show how hard it is to find real chemistry with another person. that would kinda hammer home how good he was for her and what she threw away when she left. it would definitely sell the narrative point that she finally realizes what she had and why MC is so important. feels kinda cheap to try and tell that story without showing her struggle with other relationships and have some frame of reference for comparison on what she has lost.
if DPC wants to be known for making mature content, he needs to not be afraid to tell mature stories even if it upsets the wannabe-harem/"canonical virgins" bros that will always play this game. you know, where people can have sex without the MC either before or after they have met him and it doesnt detract from their characters at all and in fact makes them more believable as people with history. he is so afraid/reluctant to show Zoey go through any of these kinds of emotional hurdles herself, so he has to make to other characters to mirror her struggles and have relationship problems that she can live through vicariously. rings kinda hollow when she isnt allowed to have any firsthand experiences unless its with MC himself
