I don't really agree with that, because jealousy is involved in the definition and that'll be very subjective. I only mention this because it's fairly obvious from feedback that some people were extremely turned-off by it (to put it nicely), and I really think that damaged the game. Because obviously for us that played it, we know that never happens again. That's why it "damaged" it, since it turned off a seemingly decent chunk of the actual player-base.
Forgive me if I forgot the details after a long time, but the game was setting her up as a LI. It informed us about her ex and how much of a dick he is, and Sarah says she would NEVER be with him again. It's clear our MC will pursue her at this point.
That is why it hit a lot of players when they're then shown a scene like that - I remember it hitting me negatively as well. But I just choked it down and continued after reading here, that it would be the only time a scene like that would show.
I think it's unfortunate, because the rest is good, and it gets better the further you go. I personally think that scene doesn't really do anything important for the story or characters, that couldn't have been portrayed in many other ways. I'm not saying a creator should change everything for the fan-base, but it would've been strategic to modify it as it is not integral to the story. I also take stuff like that into account with what I create.
All that being said, the art style was something that grew on me. I wasn't super into it at first, and I imagine it's the same with many others. I would guess that also had many people avoid it, even if they would've ended up greatly enjoying it if they gave it a chance.
