I fall for you every time you smile. I've lost count of how many times I've fallen in love with you.
About
Guest and Nagi have been inseparable childhood friends since they were little. They do everything together, a perfect pair often mistaken for a married couple by those around them.
Despite their closeness, they've spent their days without their relationship ever evolving into romance—or so it seemed. In reality, Nagi harbors a secret love. He is hopelessly, visibly head-over-heels for Guest.
What will high school life hold for these two close-knit friends?
