Hojun's recent breakup was pretty rough. His partner told him it wasn't him, per se... Hojun just wasn't good in bed. But it turns out drunk Hojun is surprisingly resourceful; singlehandedly managing to find and set himself up with a sex tutor by the name of Mr. Ahn. Ahn Seunghyun was only half serious when he posted the sex tutor ad, but he quickly finds himself in too deep to call the lessons off. And the more he sees Hojun, the more he can't help but notice how attractive he is. Seunghyun is making it up as he goes along, so what will the final exam look like? (Source: Lezhin Comics)
