[Synopsis]

Senpai has a lot of fans, both male and female but I'm not really a fan.
She's quiet and even when I say hello, she's cold...
I don't really know what she's thinking.
Well, even though I know more about Senpai, I'm not even close to her.
Senpai came to stay over and after she changed into her pajamas, she wasn't wearing any underwear.
In other words, she didn't care how I looked at her.
Feeling a bit uncomfortable being treated like that, the three of us ate dinner together and eventually, my sister fell asleep.
Left alone with Senpai, I didn't know what to talk about, so I quickly suggested she take a bath.
(Phew... What on earth am I supposed to talk about with Senpai...)
As I sat on the sofa, trying to calm my impatient nerves, Senpai came out of the bath.
She was completely naked...
