The reason Anya was acting this way and was not having her usual composure was because her love for her sister was fierce—but her devotion to Mika was something else entirely, a fanatical worship that bordered on obsession.
Yet, no matter how much it grated her to see Charlotte hugging him, Anya wouldn't dare act against her while Mika was present. His rules were ironclad.
So even if both of them stripped down and started bangin each other on the spot, she'd only bite her teeth, look away, and swallow her rage.
But still, Mika knew her too well, her psychopathic tendencies meant that suppressed anger would find another outlet, and that thought made him wary.
To defuse the tension, he made a snap decision, letting go of Charlotte with one hand and, to Anya's shock...catching her by the waist, pulling her into a hug.
