Employee dormitory where new social worker "Shogo Inui" lives.
There are two very nice guys out there.

My dorm mother's "Mr. Nagano walking" is a fancy, reliable older sister skin.
"Reaga waveaga" who lives in the next room is gentle, blessed blonde beautiful boss.

The new life with two people was fulfilling for "Shogo"!

...... But the daily life for "Shogo" changes even more.

What?
One day, "Goku walk" and the next day "Reina" -.
From a hurry to have a relationship of the body!

"Oh, there is what I am ... ... to give other hands a hand ......"

"You talk about something like her, you and he are just relations between administrator and inhabitant"

"If you say that, Reina 's the only thing to do with your boss and subordinates, do not face her!"

Apparently the two do not feel like finishing the relationship with "Shogo" only once!
A sweet relationship with a bit of a bit of two wonderful "sister" and "Shogo", thus begins!
