Straw is crazy too
Shes framing him as a thief, which will follow him for life and ruin his reputation. And this B doesn't think shes going too far? B, you want him to join your team, essentially asking him for a favor, and to get it you decide to frame him for a criminal act? Really hope this B gets what she deserves and the MC does NOT end up with her. This behaviour of hers is so far over the line I'd physically slap her for it.
