Horror World: The Foolish Beauty Is Forced Into a Love Triangle

[Infinite Flow / Fan Favorite / Rivalry for the Female Lead / Mad Dog Male Leads / 1VN] [Three years ago, on the eve of the college entrance exams, senior Shen Zi'ang jumped from the school building, staining Yusen High School with blood.] [Three years later, five of Shen Zi'ang's friends receive postcards from the past. They gather here and begin reconstructing a case with no survivors.] Timid Tang Ruan, afraid of ghosts, tugged at her oversized school uniform and asked, "Th-then, what role do I have?" [1748: You're Shen Zi'ang's beautiful ex, two-faced and dating N people at once.] [1748: Shen Zi'ang loves you so much he's gone mad. He wants you to go down and keep him company, so be careful. Don't let him catch you.] Tang Ruan: Why do I have so many qualifiers? Tang Ruan felt that something was off about this world. Who would ask their innocent ex, in a gloomy school with only five people in it, "What's wrong? Who are you thinking of when you look at my face?" Th-this is terrifying! The Beautiful Wife of the Asylum [This is the largest asylum in City A, and many 'monsters' live inside.] Tang Ruan: So what am I this time? [1748: You're a bad woman who cheats on her husband.] The Arrogant Duchess of the Grand Castle The game is underway; the instances change at random. CP: A mad-dog love rivalry, monster male leads x a pale beauty with long legs. I'm a spoiled little darling, a sickly female lead. Reading guide: Sometimes she plays the pig to eat the tiger, but most of the time she just relies on 'Husband/Big Brother, save me!' The logic is self-consistent. Please don't overthink it.
