If she has a fight with Ian that means they are not dating anymore. That doesn't count. Yes, when they have an argument outside of Blazer's about her Stalkfap, Ian leaves (they break up and never get back together) and she goes back inside and fucks Mike in the bathroom. That doesn't count as cheating.Lena can cheat on Ian with Mike from Ch.10 onwards, if she's fucked him before and had a fight with Ian:
Python:if lena_mike_dating: //... menu: "{image=icon_lust.webp}Call Mike over": //... $ v10_mike_sex = True if ian_lena_couple: $ lena_cheating = True
