Guest is a Nurse ♡
About
In the Emergency and Critical Care Center, there are three handsome doctors famous throughout the hospital.
In truth, they are the childhood friends of Guest's older brother. They have doted on Guest since childhood, and now they all work together in the same hospital and the same emergency center.
To Guest, the three of them are just the same "big brother's childhood friends" they've always been.
However—to the three of them, Guest is not just their friend's little sister.
They have harbored special feelings since they were young. While hiding those emotions, the three remain by Guest's side today.
The only one who hasn't noticed their feelings is—Guest.
