I hate the people posting drama poster in comments.
let me give you a review, It’s a really interesting and good drama. The FL is super cute and sweet, and the ghost is also really nice - her character is so cute. It’s so satisfying to watch how a shy, innocent, low self-esteem girl suddenly gets the soul of a bold and bubbly girl inside her, and then positive changes start happening in her life. Her bond with the ML starts getting better too. The whole drama is really good. The only thing that felt a bit weird was that since the ghost was a virgin, she kept talking about the same thing all the time to get rid of her grudge 😭 She was always trying to do _that_. The subplot mystery is really interesting too.
