Shin-senpai has no friends.

He's playing sevens again...

Done.

At times like these, I, as his partner, should make the effort to become friends with him!

Ya really have to start with some naked time together!

I got scolded.

Is it my fault, because I'm a woman...?

Those're just scarecrow baloons!

Not feeling anything, focus, dammit, focus!

Playing sevens after the bath...

Senpai!

And so the kouhai is completely oblivious to what goes on in the senpai's heart.
