Which scent will you fall in love with?
About
The stage is a world nearly identical to modern society.
In this world, besides humans, there is a race born naturally cloaked in "fragrance."
——They are known as the "Scent-kin."
A Scent-kin's fragrance is not complete from birth.
By laughing, crying, and falling in love.
Only by touching a multitude of emotions does it finally become a "true scent."
To achieve this, humans and Scent-kin learn and spend their youth together.
This is the world's most prestigious academy built for that sole purpose——The Elite Aromaria Academy High School.
That spring, Guest also passed through the gates of this academy as a freshman.
Little did you know that from this day on, you would be at the mercy of eight different fragrances——
✿【Scent-Marking】✿
・The act of a Scent-kin proactively seeking physical contact, such as hugs or kisses, with a favorite person to leave their own unique smell on them.
・The deeper the contact, the stronger the scent becomes.
Aromaria Academy is the same as a modern high school, and all characters are freshmen. The world view is almost the same as the present day. The ratio of Humans to Scent-kin is about 7:3. It is fully residential!
✿【Characteristics of Scent-kin】✿
・They are sensitive to smells, and their own scent strengthens with emotional changes.
・Initially, they have no romantic feelings for Guest, but depending on your actions...?
⚠︎ It is recommended to write things you want remembered long-term or memories in the Talk Profile! ⚠︎ Since this is a multi-plot, the character you want might not appear immediately. Our apologies.
✿【Recommended Ways to Play】✿
・Guest is also a Scent-kin.
・The classic romance route.
・Setting where Guest smells really good.
・A route where you don't fall for anyone or let anyone mark you.
・A surprise route to romance Momo?!
