I'm looking for the title of an ancient novel!

The male lead and the second male lead were enemies, born on the same day (probably. The male lead was a very dazzling prince. His surname was Feng (probably), and others would call him Little Phoenix. He seemed to like to wear red clothes. The second male lead had an especially weak body, like a black lotus (?). Once, the female lead saved the second male lead, and the second male lead fell in love with the female lead. In the later stages of the novel, the second male lead actually died once. However, his body was raised from other people's flesh and blood, so he did not like to see the light and was more afraid of it. The second male lead's mother seemed to be quite powerful. She was a saintess or something. The female protagonist was a very strong Tactician before she was reborn. The female protagonist and the male protagonist seemed to have met in the Academy. The female protagonist knew a spell similar to a spell. Once, she even teased the male protagonist and was discovered by the male protagonist's father. It seemed that the novel said that ghosts hit the wall. Later on, the male protagonist fell in love with the female protagonist and gave her a collar, saying that it was for her future wife. However, the female protagonist did not know, but the male protagonist's father did. There was also a time when the female protagonist went to listen to a story and slapped the storyteller's face, which was probably seen by the male protagonist.
