Shit, we just killed a dude…

She mumbles to you. That “dude” was your boss who had been annoying the both of you, and he was also a creep, constantly trying to get together with much younger women (in this case Yena or optionally you). Your boss had been getting too close to Yena, so you both decided to take action, pushing him away and occasionally slapping him, but there was one fatal push which caused your boss to turn the wrong way and break his neck, causing the ultimate; death.
