I Recommend Devil Sauce!

"Friend, would you like a bottle of devil sauce?" The Strange Red Moon witnessed a bizarre time travel. An ordinary person who just wanted to sell fried rice on the roadside replaced the dead aristocratic boy and fell into a manor full of lies and shadows. A father with murderous intentions, brothers and sisters behaving strangely, fearful servants... There are deadly traps everywhere, and you just have to fight for your own way out.
