Shirasaka invites his junior Yuka over to his house for some drinks, and he complains to her that he still couldn't get himself a girlfriend, two years after entering college.

The dense Shirasaka tells Yuka that he thinks of her like a sister. He's been her unrequited love ever since high school, and she even entered the same university as him; but he just won't realize her feelings, and this got her feeling down. To cheer herself up, she takes a toilet break, and when she came back she was in for a surprise: he has fallen asleep and at the same time, he has a bulging erection between his legs.

Yuka couldn't take her eyes off his crotch, and instinctively takes off his pants...
