Haeun’s longtime guy friend Dojun has an oddly empty dating history.

Sure, he’s quiet, a little timid, and kind of drab… but with a decent face and build, why has he never dated?

Curious, Haeun keeps prodding—and uncovers the surprising truth:
whenever things get intimate, he just can’t get it up!
Her friend is the “won’t-stand-when-it-counts” type she’s only heard about?!

Haeun decides to help Dojun herself.
But what starts as hands-on “lessons” to coach him takes an unexpected turn…

“Yoon Dojun—can I be the one to take your first time?”
