Original Webtoon

[Dashing Younger Gong Nam-hyuk X Grumpy Older Su Hosu] Hosu, a returning student who always had good luck, ends up spending a night with Nam-hyuk, a freshman he met at a drinking party. However, his satisfaction with their amazing encounter is short-lived when a glowing pattern appears on Hosu's stomach, causing Nam-hyuk to scream as if he's fainting. "I-I think I accidentally put a curse on you, Senior!" It's shocking enough to find out the person he spent a night with is a witch, but the method to break the curse is to regularly receive the witch's semen? Isn't that a bit much? Wait, is this really effective?!
