Can't Friends Do It?

Seol Ha-Eun has always been puzzled by her long-time childhood friend, Yun Do-Jun. Despite his quiet, introverted nature and somewhat gloomy aura, Do-Jun is far from unattractive, he possesses a solid physique and a face that should easily draw romantic interest. Yet, strangely, he has remained perpetually single. Driven by a mix of genuine concern and relentless curiosity, Ha-Eun finally corners him for the truth, only to be met with a shocking confession. It turns out Do-Jun suffers from a debilitating secret: whenever he attempts to get intimate with a woman, he simply cannot perform. Stunned to discover her best friend is a "broken man," Ha-Eun impulsively resolves to take matters into her own hands to "cure" his dysfunction. However, what began as a clinical, hands-on lesson soon spirals into an unpredictable, heated entanglement. As the boundaries of their friendship blur, Ha-Eun finds herself whispering a daring proposal: "Yun Do-Jun... would it be okay if I’m the one to take your virginity?"(Source: Lezhin US)
