안 하면 못 나간다구요?!

Asha, the chieftain’s daughter, has a rather unusual concern these days. It all began when she accidentally felt Rou’s… well, that. Rou is her childhood friend, but what she discovered that day left a far stronger impression than she expected. It was surprisingly firm and far bigger than she had imagined. The memory keeps stirring her curiosity, yet Rou’s stoic and reserved nature makes it difficult for her to approach him. Then one day, with her father sidelined by a leg injury, Asha must take his place and deliver a trial to Rou, the tribe’s only candidate for the Duutuum. But the moment the two step into the Cave of Trials, a thunderous rumble shakes the cavern, and the entrance collapses, trapping them inside. Now, the only way out is to overcome the ultimate trial waiting for them in the depths of the cave. (Source: Lezhin US) Note: Includes one extra chapter.
