I wasn't going to reply to you but there's so many points I want to debate. Anyway, your post could use some paragraphs and a spoiler alert but:
Then make a fanfic. Starke stated he couldn't see Jack and Ayame be a thing
now. If there's a Fleeting Iris 2 which I hope there will be, then I'm pretty sure Jack will become an even more important character with some happy endings.
So you expected them to keep writing the story for at least three more in game years, create new sprites for a 3 year older Jack and probably a 3 year older Ayame, etc. just to have an happy ending? A 4th potential Jack ending.
That sounds more like DLC stuff, send them a message in Discord and suggest it.
What?
Jack is.
Two wrongs don't make a right. Right or wrong is an absolute state. He's not "less wrong", he's wrong. Her "moral debt" if any is to Robert. Doesn't make it right for your stepson to blackmail you just because you got a thing for your grandfather's ding dong. Jack "technically" raped her. I'm not saying Ayame didn't have feelings for him but they would have to be developed further because not only she would be breaking up with Robert, she would be breaking up with Robert to date his son and in Family Route other than "he's a shitty shagger" she has nothing against Robert.
It was, until he screwed her over like an immature child over and over again. Jack couldn't do any better, it was his personality and completely in character to do those mistakes.
Mate, who the fuck invites friends over to hide in the closet so you can prove you're shagging some girl? That's typical teenager shit and those attitudes are what made a gap between Ayame and Jack.
She's 23~24, what lost youth? And what would she rediscover? Dating little boys?
She can still date and have passionate full balls to the wall relationships typical from someone who never had her heart broken right now. She's a child
now, experiencing a lot of these things for the first time. That's part of what makes her naive and immature.
I don't agree with the details but I do agree that a DLC would be fun. Worth it? Dunno mate. Maybe they didn't explore their relationship more on purpose, so it's a thing in Fleeting Iris 2 when he's actually older, matured and possibly can provide for her.
The fact that the game touched you in such a way is a win in my books and why I like it so much. Just start a #TeamJack thing and make sure he's a major character in a potential second game.
I just find it mildly disturbing you'd rather vent off here than in their official section on the official discord dedicated to posts
just like that where they can be read and debated by literally the only few people that can do anything about it, and trust me when I say that they listen and cater to their community's wishes more than any company I've ever seen. I can tell you a dozen scenes that I remember being in the game just because people got together and voted for it to be a thing.
