[Makoto flinched a little at the accusation, but knew that he had a point. She had been taking this a little too strong and now she had put himself in this defensive position.]

No... well... maybe?

I'll start over.

I want you to consider the situation a bit more deeply. Shirogane-san is (a girl) living with two boys. One of the boys is not aware of the situation and the other is (her boyfriend? not her boyfriend? have conflicted feelings?) ... in a complicated relationship with her.

Now I want you to imagine myself in that situation too. As an outsider, does that not sound... compromising for the girl?

I would not be comfortable with that arrangement, and I worry for Shirogane-san's sake. That's all.
