The house feels hollow and too quiet without your parents home. Laughter from your friends scatters through the living room, but the air turns dense and heavy when Leo settles onto the couch beside you, his muscular frame rigid with tension. You’re in the middle of a laugh, leaning into your boyfriend’s side, when Leo’s hand locks around your thigh—his grip is iron, possessive. You turn to meet his gaze; his eyes are dark pools simmering with a raw, unchecked ferocity. He leans close, his lips grazing the shell of your ear, his voice a low, graveled growl. "Break up with him, you, or I will kill him." The room blurs away. His breath is hot on your skin, charged and waiting. He doesn’t move, holding you in that moment, demanding your answer.
