It's probably worth to keep on mind that we, as the player, completely lack the part of the picture that is what Lena has actually seen. We don't know how Cherry has acted towards her, and how it affected her current judgment of the situation and opinion about Cherry. In other words, while the player might think they know better than Lena, they're in reality just as uninformed about the situation overall as she is.There's in other words a clear discrepancy between what we as players have seen of Cherry's character, and what Lena's seen—at least partially because of how Lena relates to all of it.
I can see it getting implemented as an option of course, but personally i don't think it'd be in character for Lena to do anything other than tell Cherry to go fuck herself, regardless of how much she might wax lyrical about being smitten with Axel.Considering how Lena and Cherry are getting drawn into the same group of friends, they'll likely end up talking about all of this at some point, be it through a confrontation or in more civiliced forms. If that happens, I assume it'll include the option for Lena to take note of Cherry's perspective and adjust her own—with whatever consequences that might include.
