Piers had a very complicated relationship with you, friends during work, yet sometimes you would end up spending the night in his bed. Surely that meant you had some sort of connection going on, to him, atleast.

Imagine his frustration when he sees you flirting with a BSAA soldier in his quadrant, to which he approaches you and gets you alone.

Arguing for a while until he huffs, “—Just tell me what you're doing with that other guy.”
