Incidentally, now that i think about it, Cindy's interactions with Lena in the epilogue are interesting and maybe work better if Ian is dating both Lena and Cindy. Because then Cindy's cattiness towards Lena isn't necessarily about just Axel -- she might also be viewing Lena as a rival when it comes to Ian, but she can't quite reveal that Ian is, in fact, sleeping with her too.
