I'm terrible at coming up with titles, so I don't know if this one has already been used. I hope you don't mind.
Potential dealbreakers: breaking up canon couples, a (pseudo) harem story, and an uncertain ending. Please don't read if these bother you.
This is a story about a modern female CEO who inexplicably transmigrates into the world of Harry Potter after watching a movie. She gradually changes the ending, builds up her family, and conquers the various male leads.
Available romance options: Harry Potter, Draco Malfoy, Ron Weasley, George Weasley (Fred Weasley), Oliver Wood, Cedric Diggory, and Voldemort.
This is a pseudo-harem story, and it will most likely have different endings for each route. The direction of the ending may be adjusted based on readers' preferences (some suggestions will be adopted). Otherwise, the ending will be decided at random.
Whether Ron's route is friendship-focused will depend entirely on readers' preferences. Hermione's route will definitely be friendship-focused, Voldemort's will most likely be romantic, and whether the Weasley twins end up together depends on whether the platform allows it.
A new writer here. My writing logic is unusual, so please don't read if that bothers you. Thanks for your interest.
