I doubt it: if Bella is really linked to Jolina as hinted, one of them is probably the second gold digger. Dunno if MC is willing to have a threesome with one of the gold diggers, then again it will probably be your (player) choice.
So far all we know about the second gold digger it's her name or nickname, Dizzy. even if the fortune teller told us it's Dizzy by name and not by nature.
sorry for the abrupt answer earlier, but I had to go to dinner and I was in a hurry.
the third heir is not necessarily an enemy of MC, she would only be so if she made MC fail to achieve his share of the inheritance
Bella with her demeanor goes to great lengths to keep MC away from both Elaine and Monica and her family, so she's likely a gold digger, but I don't think she's the third heiress.
Could Jolina be? for now a few elements, she too seems manipulative like Bella, but this tells us little. I am quite convinced that she dropped both Jenna and Mc where she wanted, pretending to be spied on without her knowledge, but we have to understand why. something will be understood in the next episode.
but if Bella and Jolina are a couple, and Mc offers both shelter at the house on the beach .. I think the road to coexistence has been traced.
then this is purely my impression: I think there will be some twists, but I don't think there will be a real bad one among the LIs, there will probably be someone who will make mistakes that will have to explain and be forgiven.
