I do hope that with Nyx's redo of Iris's path in the next update, that means we will actually get to have a serious talk with her at some point, where she reveals her true feelings. There's alot of dancing around it, especially while on the Lexi beach double date. Iris trying her best to be happy for her friend Lexi, while she's with the guy she still loves. It hits even harder if you see the extended scene with Iris after the club, where she almost sends "I still love you" to the MC.
That scene is way too easy to miss btw, Nyx needs to change that IMO.
