How about we stay just friends?

Haeun’s long-time male friend, Dojun, has surprisingly never had a girlfriend. He is a bit shy, introverted and gloomy… but he has a good-looking body with a decent face, so why has he not been able to date anyone? Out of curiosity, Haeun thrusts the questions at Dojun—until she discovers the unexpected reason. Apparently… every time he attempts to have sex, he cannot get it up! Her friend is the thrice definition of what people call, an impotent man?! Determined to help him out herself, Haeun ultimately decides to take matters into her own hands. But what starts out as an innocent “lesson” to help out Dojun quickly shifts in another direction… “Yoon Dojun, can I be the one who takes your virginity?”
