[SOLVED] Need help remembering a manga

[redcrown97]

The premise is the mc was thrown off a balcony and dies. Gets revived somehow but has to find her killer within 7 days.

• MC is the monarch of the kingdom
• Fairy King or equivalent revived her
• Primary suspect was her ever-cheating prince consort
• Her guard knight is also a suspect
• Her maid also died of suspicious circumstances
