I get that some people want a girl who is experienced and wild but see the story from MC's POV. She's was MC's crush even before this FL thing started and there's a reason why he's still sticking to lydia even though he's surrounded by a lot of girls. As much as i like sex in games i also like a genuine love angle and lydia brings that for me. I never found his infatuation boring. Maybe because i am into innocent and naive girls like MC but i can understand why people aren't so fond of lydia. It's all about preference. I just don't get the hate lydia get. It's not even like she's an obstacle.
I get that. I am like you actually, I prefer the characters that seem more genuine, rather than just a superficial relationship. However, the "cuck-queen" angle has been done to death in other games, so I am dissapointed that it is showing up here. It doesn't fit with her character to me. I wish Vinovella made her more like Min with some off-the-wall fetish (the game is called Fetish Locator after all), that the MC can awake in her. That would at least make her interesting and fit in better with the overall theme of the game.
I think overall Lydia has potential, but with all the other characters, I just don't think she will ever get enough screen time to really develop her better. If all she is in FL, is someone to tell about all the fun the MC is having with other girls, I don't see the point.
The main problem, really, is that she doesn't fit this game, so whenever she shows up it is disconcerting for the player. If the game focused heavily on Lydia from the beginning, and just used other characters as a side outlet, like Haley's Story or Life with Mary, for example, she would be more appealing. But she was introduced late, and doesn't have any interesting back-story or motivation. For examply, why does the like the MC at all? They barely know each other, go out on one date, the only thing the MC really says is that he likes her singing, and then she finds out he is sleeping around with all these other women, including her friends, and she sees the MC as a great partner for her? If the dev developed her character much more, so at least we could see something that they have in common, or some shared history, or some reason why she is interested, it would make more sense. Maybe he can help support her singing career, or help her find more success. But then it would be a completely different game (like Melody).
But, honestly, the rest of the game is great, so I can just zone out a little on the Lydia scenes, so I don't mean this as a major issue. Just something odd about her character I think many of us have noticed.
