When I woke up, I found that there was a beautiful girl in my family. Is she the male protagonist's long-lost sister or his future wife? I wanted to spend this life peacefully with her, but why did things go against my wishes? I always encountered various difficulties and dangers. How to choose between liking someone firmly and being liked by someone firmly? Should this be called luck or misfortune? Perhaps, I have already given the answer, that is, no matter how many times I reincarnate, I will save you from endless suffering, even if it costs me my life, but as long as you are alive, I will be safe!
