Every Day I Wake Up in the Middle of a Major Disaster

[Features a major love-triangle showdown / a goofy, unconventional reverse-harem romance] Straight version: Muse completed her mission perfectly and successfully returned to her original world. She had no grand ambitions. After weathering so many storms, she was ready to live an ordinary life... But who could have guessed? Holy crap, her original world had merged with other dimensions? Σ(°△°|||)︴ Male leads from the interstellar world, the cultivation world, infinite-loop stories, historical settings, apocalyptic worlds, online games, and more are all rushing over. The countdown to a massive love-triangle showdown has begun! Watching all the male leads arrive, ready to fight, Muse suddenly fell silent. The male leads from all the different worlds: #What do you do when you wake up every day and find out your partner is cheating on you? Help, answer urgently?!# Drama-queen version: #I absolutely refuse to admit that the person in front of me is my love rival# #Why do I wake up every day with green hair that glows# Every male lead thought he was Muse's one and only, her precious sweetheart, her darling... But who could have guessed that Muse had other guys on the side, and not just one! Muse never expected she'd actually get caught out one day. Looking at the showdown before her, she felt like a total player caught cheating in an online romance. But how could she possibly admit to that? So Muse gave a strained laugh and backed away a few steps. "Actually, I think we can still work this out..." A split-personality, darkening, jealous, possessive male lead X a quick-witted heroine with a powerful survival instinct [PS: No one or anything is disparaged in this story, only the characters' actions. One-on-one sweet romance, and the heroine is not a player! The author writes however the mood strikes. If you love my story, stay up all night with the moon, and you'll be my little bald sweetheart~]
