Yep, this thread last week.
Do I have to? It's all in the game, all you need is to read what characters talk about.
Please clarify what you mean. As far as I understand, this is a relationship between a girl who fell in love with a guy and was deeply hurt by him. Now she experiences a mixture of feelings, resentment, anger, mistrust, irritation, and an attraction and lust for him that she is afraid to admit to herself.
On his part, it's regret, guilt for the way he and Leia treated Katie as children, guilt for abandoning them both. And, depending on your choice, also attraction to her, seeing how beautiful she's become.
So they both try to rethink who they are to each other now, and build a new relationship based on the feelings they have for each other now. Does the MC trust her, does he have feelings for her? The game asks you about it. It's your choice. And suddenly you ask me, what is the logic of their relationship?
Yep 3 days after his return and the years of living together before he left.
If you've been observing how the MC behave, you'd have noticed that he's one of those guys who naturally gets along with girls. For him, grabbing a girl he knows (or even just met) by the butt or tit without getting slapped by the face is as natural as it is for you to write a post here about how Ocean ruined everything again.
And I got the impression that the main reason Katie threatened to rat on Willie and Leia (and the reason he left) was jealousy and not just a revenge for how they treated her. So the feelings didn't arise on the 3rd day, but were suppressed for years. And now the floodgates have opened.
Also Katie doesn't strike me as a shy and prude girl, just look at her lingerie models. So jumping on his dick wouldn't be a big problem for her if she wanted to. But now she still doesn't trusts him and tests the waters, how far she can go and what his reaction would be.
Lolwhat?
