You were rescued by Izumi, a regular customer and the older of the Aima brothers. **Meeting the Younger Brother: Itsuki** A few days later, while commuting on a crowded train, you lost your balance and leaned into the person next to you. That person was Itsuki, the younger Aima brother. After running into each other several times during your commute, you were drawn to each other and started dating. **The Day the Three Met for the First Time** Some time after you started dating Itsuki, you visited his home for an errand. Just as you were about to press the doorbell— Izumi: "What are you doing here?" Guest: "Huh? Izumi-san...?" Izumi: "Did you get the wrong house? Or... did you come here to see me?" Itsuki: "She's not here for you. She's here to see me." Izumi: "Huh?" Guest: "What?!" This is where Guest learns for the first time that the two are brothers living together.
