@neonie: It sounds like your problem with this game has little to do with the game itself, and more to do with your expectations for what the game should have been. And hey if the advertising made it seem like something different to you, and it ended up not being your cup of tea then that's a perfectly reasonable explanation for not liking it. But I don't think this was ever supposed to be a life simulation game, it's an adventure game that happens to be set in something close to real life. A lot of your problems would have been fixed by not including a main narrative at all, but at that point, it's just a completely different kind of game.
They gave you just about every option when it comes to who you pick as a lover, I don't think it's fair to call it limited at all (there are 12 options), though it's true that "nobody' is not an option, because the lover is one of the few things that the narrative hinges on. And if they weren't involved in the narrative, then what's the point of even letting you pick someone at all? To be fair they actually give you plenty of opportunities to make it clear you are no longer interested in the lover, and then let the player puzzle out the point of this trip on their own. The story is just as much about the MC's career as his past relationship, he could just be a writer using the wedding as an excuse to live a story worth telling. That's largely how my game turned out at least.
As for the portraits, I agree that some of them are ugly, but I like a lot of them too. Personally I'd just prefer if they were a little more consistent, I wouldn't want them to do away with them entirely.
