I reckon her problem was independence. She wants to move away from her sister and the sister's husband's household. For a few reasons, one of which is not being an economical burden and the other that she can't apparently help but like her sister's husband (like Ryll said), who in turn is a very gentle and friendly person, and no doubt that makes Saki feel like she's betraying her sister. And the other side of the independence is to move on in the society, that is, get a job now that she's graduated.

I feel bad for Ohsugi, even if he isn't a great character. It would be bad if they had that buildup but were unable to save him.
Or this all could be just to get one more player removed from the game. Ohsugi might be a sacrificial pawn in the plot.
