Real or Fake Daughter? No, I Want to Become an Immortal

Although the heroine chose to immigrate to District 10 because District 10 is the most accepting of her immigration status, the heroine's original family is a local leader in District 10. Since the heroine came to District 10, her identity as a time traveler has been deliberately revealed, which has threatened her personal safety. Moreover, the heroine often meets people from her original family when she goes to school. I took a look and found that after the heroine came to District 10, in addition to going to school, she had inexplicable contact with her original family, and she would meet people from her original family unconsciously. So I still don't understand why the heroine chooses the tenth district. Although the treatment is the best, it is a lot of trouble. She could have chosen an area other than the tenth district with the best treatment.
