Across the Hall

When Isagi Yoichi moves into Apartment 304, all he wants is a fresh start.
When Itoshi Rin hears the moving boxes crash into the wall next door, all he wants is for the noise to stop.
Neither of them expects that one knock on the door will change their everyday lives.
Between convenience store runs, accidental package deliveries, rainy nights, and quiet moments in the hallway, home begins to mean something neither of them expected.
Or:
The one where Rin falls in love with the boy across the hall.
