Im searching this reincarnation princess manhwa. She was the real daughter of the duke but someone claimed to be the real daughter. In the past life, She goy manipulated, and did the worst decisions that made people be suspicious that she was the fake princess and then turning point was suddenly, she couldnt control the spirit of the water Undin while the fake one was able. She was sentenced to death after bring accussed of being the fake one. When she got reincarnated, she did things pretty well and started to counter the things the fake sister do then i forgot it UnU.

Here are some of the scenes i remember.
1. There was a scene that the fake sister woke up everyone on the aunt's house cause she thought the real one was stealing liquor but she didnt know it was the maid of the real princess.
2. There was a scene with church where they had two things to protect. One is like a cub, and the real one is a chalice. The fake one started gathering people and made her maid destroy the chalice but the real princess told her maid to put the cub on her room to make it look like the cub was the reason why the chalice got broken.

Please help me
