An Island with Only Gyaru and Otaku

Yumesaki Wakana is a blonde gyaru who sits at the top of the school caste.
As an otaku, I thought she and I belonged to completely opposite worlds.
However, in a classroom where she happened to talk to me, we happened to discover that we shared the same hobbies, and our relationship quickly grew closer.
Before long, as we began to harbor faint feelings for each other—like a mutual unspoken crush—
cracks started to form in our happy days, caused by the hands of another man…
 
 

A group of schoolgirls, all renowned beauties even within the school.
By chance, they began hanging out in your room regularly.
Now, day by day, different girls come and go in turns.
After school, they drop by, spend some time, and then leave in a hurry.
In return for letting them use your room freely, all you get is just a bit of casual skinship.
At first, that was the extent of your relationship.
However, as you shared trivial moments, conversations, and touches, little by little…
Eventually, both you and your room became an irreplaceable “place” for them.
A special and naughty everyday life, woven together in a single room.
Would you like to experience those moments yourself?
