Celebrity (2023)

When Joon moves into his new apartment on his first day of college, he wasn't expecting beautiful ex-celebrity Duna to be living downstairs. Joon tries to avoid her at first, but finds himself growing more and more curious about her mysterious life.

i think the vibe is quite similar, all of the story is begin from the poorest to the highest. but maby Anna feels more darker than Celebrity because the character 'Anna' is more unhonest than this Seo A Ri. We will find the same feeling about Psychology Thriller from above the two dramas.
