Does anyone know which comic or novel this is?

In the beginning, there was a samurai who killed a dragon in order to meet the God of Samsara and ask the God of Samsara to help him reincarnate, because he accidentally killed his girlfriend but loved her very much. The God of Samsara told him that he would regret it, but he didn't believe it. In the end, he really reincarnated, but he turned into a girl. In this new home, he had a younger brother and parents. He had two kinds of memories, one from the present and the other from the previous life. In the modern world, he still knew kung fu. He found out that his girlfriend and he were in the same school. He seemed to be drawing, but he wasn't good at it. There was a boy who saw that he knew kung fu and even acknowledged him as his master. In his previous life, he had a woman who liked him and wanted him to return to her side until now ~~~~ I've read this before, but I've only read half of it. I still miss this manga and want to read it all. Is there any expert who can help me? I'm very grateful!!!
