Reincarnating... Again

PS: I didn't know what to do as a cover so I went with Haruka. Okawa Takahiro... He was a normal human from Earth. If you don't include the fact that he's insanely smart. Not only that his will is strong. The reason why? Welp he's lived 999 times... Not only that... He remained a bachelor... Now it's his time to get rid of that status! Until right before... He died... He reincarnated again... But this time... He wasn't on Earth anymore...
