Spare Me, Sis! Reborn in Tokyo as the Ultimate Romantic

Novels About Protagonists Reborn in Japan

I'm looking for stories about someone reborn in Japan or a parallel-world version of Japan, with a focus on everyday life or the entertainment industry. Ideally, the protagonist can cultivate immortality. Something like "Reborn as a Japanese High Schooler: Li Tong", "A Girl Next Door Has Come of Age", or Liu Sanmiao's works.

The Protagonist Transmigrates to a Foreign Country and Becomes a Foreigner, Any Country Is Fine

I just can’t get past this: they transmigrate to a foreign country, to the West, and still use Chinese names. It just feels weird. So could you recommend something where they completely transmigrate into a foreigner? If they’ve gone to another country, then let them be foreigners, not Chinese people.
