Given the communication breakdown that is often at the core of drama in this game so far, I'm not going to expect a clear sign from the girls as to when enough is enough regarding the mc's philandering ways.
Even though Maya and Josy discussed the openness of their current relationship with each other, both are not happy when the mc admits to flirting when Becky joins them at the lunch table.
And that's the thing, just because you're allowed to do something, doesn't mean people will appreciate it...
The discussion of their relationship puts all the pressure on the MC's back. Josy and Maya are already in a relationship, it is not they who are going to look elsewhere.
M + J say: "We are not forbidding you anything, but whatever you do will be the illustration of how you feel (or not) for us."
So if we want to follow the M + J path, we will have to be discreet if we fool around.
