Replaying this game to setup saves for the next update, and I have to say I don't like how Ian's infidelity is handled from Lena's side of things. On Ian's side, he can find out that Lena's been "going around" in general, hooked up with Jeremy (late relationship route only), and I believe he can find out about Axel as well. From there, if he hasn't committed to Lena yet, he can choose either look past it and still go for a relationship, or decide to end things (unsure in the case of Axel). Or, if they've committed from earlier on, he can either dump her, forgive her or open it up if he is a cheater himself (again, unsure about Axel). A nice range of options.
Lena meanwhile? She can only find out about Cindy, and if the affair is still ongoing Ian can either lie or tell the truth, and if you decide to tell the truth that's too bad, Ian gets auto dumped no matter how much Lena loves him. Can't even ask for forgiveness or promise he won't act out in the future. That's the early relationship route, and in the late relationship route he just automatically lies lol. Why? Why is the range of responses here so limited? One can make the argument that the Cindy affair is unforgivable because Cindy isn't just any girl, but then again Ian can forgive Lena over Jeremy even though that's a pretty similar if not outright worse situation.
But that's just Cindy. Out of all the women Ian can sleep/cheat with, why does Lena only find out about Cindy? Ivy could have easily told her that she heard "Ian is a player and fucking around with multiple girls" behind her back or whatever, and Lena could have been granted a similar range of options Ian had, in terms of how to respond. As things currently stand, there is no drama for a cheater Ian, he'll likely just keep lying and cheating until the relationship inevitably tanks because of it. Since Lena can currently sense an unrepentant cheater Ian is getting increasingly more distant, it seems to me that things will keep deteriorating until she finds out and dumps him on the spot, and that would be so disappointing.
For me, ideally there would be a future Lena POV chapter which puts her in a crisis the way Ian was in the beach episode, with a similar range of options on how to proceed. Unfortunately, that doesn't look very likely because it seems to me that the beach trip was the ultimate point where the status quo of the Ian x Lena relationship can be fundamentally changed or reaffirmed.
Still hoping for a Lena Cindy catfight over Ian at least, Lena meeting Cindy right after finding out about her affair with Ian and nothing coming out of it was a huge missed opportunity.
