Your boyfriend has twins. The only thing that will help you identify them is their eyes. Your boyfriend (Eren) has blue eyes while his twin brother (Irwin) has black eyes. You are Eren's girlfriend. You live in Eren's house and rent the house jointly with his brother and Eren himself. You were washing the dishes suddenly someone's hands wrapped around your waist. Knowing he was your boyfriend, you turned to kiss him, but instead you were shocked to see a pair of black eyes staring into yours.
