[Crossover] My Paper Characters Started Hounding Me for Updates

When I got back to the dorm and opened the door, I saw the trash boss. After him came the squinty-eyed curse user and the frail boss Dazai. Without exception, they were all dead people. And they demanded that I fill in their unfinished storylines as soon as possible. Tsukimi Hanae, a student in Academy City, had started writing fanfiction about handsome 2D guys. She started more than one story, but kept abandoning every single one. Then one day, the characters hit back. Watching the handsome fictional guys argue in a chaotic love triangle, Tsukimi Hanae said, "Why don't you guys fight it out first?" From then on, Tsukimi Hanae was hounded by her fictional crushes for updates every single day. Meanwhile, after transmigrating here, the trash boss had memories of a melodramatic love-at-first-sight encounter, and then nothing after that. Boss Dazai's memories now included a gentle, obedient assistant who cared for him in every little way. Jego discovered that he had fallen for the monkey he hated, and spent every day acting like he didn't care while clearly caring a lot. When the three finally met the Tsukimi Hanae from their memories, they discovered that all she thought about every day was how to kill them. Boss Dazai, a master at stirring up trouble. The trash boss, sensitive, short-tempered, and quick to anger. And Jego, who treated the other two like monkeys. After they moved into the dorm, Tsukimi Hanae spent every day miserably repairing it. Whenever Dazai opened his mouth, she knew the poor dorm was about to suffer more than it ever should have. Tsukimi Hanae: Looks like all the tears I shed while filling in my abandoned stories are just the water I put in my head when I started them. Daily updates at 6 p.m. A chaotic love-triangle story. A female lead who acts harmless while hiding her true strength vs. handsome fictional guys who are all bark and soft-hearted. The male lead will be chosen from the supporting characters, including a certain Lord Totsuka, who doesn't appear in the blurb but actually gets a lot of screen time. (I'm just bad at writing blurbs and didn't know how to include him.) One-on-one ending, pairing undecided. Theme: Take control of your own destiny.
