Being an Idiot Is How I Save the World

Side Character A, initial stats: Strength: 9 (Max 100, can increase) Intelligence: 9 (Max 100, can increase) Beauty: 85 (Max 100, can increase) Saintliness: 10 (Max 10, can increase) That's right. Due to a manufacturing defect, his idiocy was supposed to have a maximum of 10, but instead his saintliness had a maximum of 10, and it could still increase. This turned a standard idiot cannon fodder character into a super saint. Fate had made him an idiot, destined to charge in one after another and provide experience points to the protagonist, his lackeys, and the villains numbered 1 through N, becoming a standard experience-farming dungeon. However... Because of the manufacturer's mistake, his idiocy became saintliness. The plot couldn't progress through his own actions, but if he didn't stupidly provoke the protagonist, the protagonist couldn't level up, and the whole world could easily end up doomed. Fortunately, under the enormous banner of saving the world, the saintly one says he'll do his part, as long as nobody actually gets hurt. Saintly idiot top x scheming, alluring bottom. Top's POV; top spoils bottom. At the start, the top has low intelligence and strength. After all, an early-stage mini-boss doesn't need high intelligence or strength, or how would the protagonist get to slap his face? Both stats can increase.
