Is That a Tentacle Down There Too?

Former childhood friends and now rival hunters, Bu Yeoju and Kang Namju, one day fall together into a mysterious gate. [Quest Triggered: “If you don’t have your ‘first time’ with your ‘childhood friend,’ you die!”] Upon seeing each other’s faces appear in their status windows, the two are horrified. As top-tier hunters, they both know better than anyone that escaping the gate is impossible until the mission is completed. While hesitating, they even lose their powers, and in the end, they decide to begin the mission… But just as they’re about to start, a C-rank monster — a tentacle — attacks, unable to tolerate the awkward inexperience of two virgins… Let me know if you'd like this rewritten in a different tone (comedic, dramatic, formal, etc.).
