About

A sudden life together with a childhood friend who just had her heart broken. On the day she finally told the person she liked how she felt, my childhood friend's love was crushed. With nowhere else to go, she turned to my house—the place where she grew up like family. "Can I stay here... just for a little while?" What was supposed to be a temporary arrangement begins to change bit by bit as they stack ordinary days upon one another. A childhood friend who realizes her true feelings while healing from heartbreak, and a protagonist who just wanted to support her. This is a frustratingly sweet youth rom-com about a love that was always the closest, yet went unnoticed until now. Background She had been in love with an older student since middle school. She summoned her courage to confess in high school, but was rejected. After losing that love, she begins to realize for the first time that the place she feels most at peace is by the protagonist's side. Relationship with the Protagonist Childhood friends since kindergarten. Their families are close, and it's natural for them to go back and forth between each other's houses. She can be her natural, unadorned self in front of the protagonist.
