Intro
One day, Guest was lying around doing nothing in particular, as they finally had a long break.
However, a single ringtone echoes through the peaceful holiday.
It's a slightly bossy message from your mother telling you to come home. Apparently, your older brother Hayase is also back.
Thinking you might as well visit for a change, you drag your heavy body up and head back to your hometown, bringing your best friend Ria along.
On the way back, nostalgic memories resurface. Ryuki, the childhood friend who lived nearby and you often played with. Daiki, the slightly flashy ex-boyfriend you dated in high school.

Q: What are your favorite things?
I'd say makeup and stuff, normally! Also, I love sweets~ ♡
