Hi!I really don't understand this outlook.(...)
I think you missinterpret some arguments here. Many Mina fans assume that Ian treated her badly from the start, so she never told him of her bucket list, which simply cannot be the case. They would not have come/stayed together if that was the case. We know that Ian can be charming if he wants to and when he met Mina, while he was already influenced by Chuck, it was not to the degree he is in the present of PC. There are several hints throughout the game that Ian until starting his selfsabotage later on, he and Mina certainly hit it off.
We even have evidance of this in the game, when it is nearly too late to do something. e.g. There is one outcome of the altercation in the disco where Mina and Ian are clearly happy with each other.
While Ian went far too far with his cheating and it does not excuse his actions, one piece of info we learn about Ian and Mina´s situation in the bedroom does paint a not so good picture about Mina as well, esp. knowing she has her bucketlist. That Ian has to rouse Mina´s jealousy by flirting with other girls to get a hotter roll in the hay with her is not a good sign.
By the time this started (in the past of the game) Mina will certainly had learned that Ian gets off on wild sex, would not look down on her for her sex fantasies and Ian would also be more than happy to experiment with her. But she still played the role of the quasi innocent, despite wanting the same kind of sex as Ian.
Mina playing the innocent role is even more obvious with Hana at the birthday. Mina and Hana click early on with each other there and it is strikingly obvious by Hana´s looks and what she tells us, that there not much which can shock here and she is a quite open girl.
Sure, you normally do not tell someone you know only a couple hours your deepest sex fantasies, but how Mina reacts to and treats Hana and Ian during the truth and dare game is telling. For example the sharp look Mina gives Hana for talking about a kink more tame than most of Mina´s fantasies she wants to realise some day. That is totally unneccesary from Mina. Or how she reacts to some other revelations in the company of people she can be sure(!) won´t think less of her if they knew her kinks and in that case they don´t. But she still plays the innocent one to a ridicilous degree. So much that Hana knowing her for just that evening cannot stop herself from teasing the hell out of Mina.
We just argue that while Ian was the main culprit of their break up, Mina is not completely blameless.
