Yoo Misol was recently rejected by her ex-boyfriend due to her small breasts. "Are they really that small? They're a full A-cup, though," she thought in a panic, wondering, "Am I destined to die a virgin at this rate? Chawon, can you truly tell if they’re fine? Give me an honest opinion, you idiot." Her childhood friend, Yoon Chawon, then suggested, "Yoo Misol, take them off. We’ll give you an honest opinion." Unexpectedly, with Chawon, whom she had known for two decades, and his friend, Jang Taegeon, who remarked, "Anyone who wouldn’t be all over you looking like this is a complete idiot," she found herself in an outrageous three-some experience that she never thought would happen even in her wildest fantasies.
