Marrying Acheron From The Start! (Honkai Star Rail)

Synopsis: I transmigrated, only to land right in Acheron's arms. The system told me to confess my feelings to Acheron. As if I, Sylvia, am that kind of person! I'd rather die right here, thrown outside— Wait, there's a Stellaron in this damned place? My apologies, I was too loud earlier. Let's discuss how to marry Acheron instead. "Acheron, could you help me perform a ritual? Don't worry, it's very simple." Even if we got married, it would only be out of necessity! I, Sylvia, would absolutely never do something so scummy! But marrying a Herta puppet... that just makes me a pervert, not a scumbag, right? Getting flirty with a game character, being down bad for a fictional persona—that doesn't count! How was I supposed to know it was Silver Wolf on the other side? By the same logic, marrying Stelle in the Simulated Universe was purely for testing purposes! And marrying Firefly in a dream? Dreams don't count! I just wanted to give her a complete life. And also... "Mhm, keep digging yourself deeper. I'm listening." The white-haired Acheron rested a hand on her sword hilt, her calm gaze fixed on the sweating Sylvia. On her left ring finger, a silver-white ring glinted coldly. "First, explain to me what these matching rings mean." --+-- — Description from novelcodex.org
