To Capture a Protagonist's Heart!

When I woke up, I was in the "Waiting World" and a Goddess appeared before me granting me two options: To reincarnate into a normal life or a life where I would be a main character in a harem anime! I was granted this chance because I was apparently virtuous! My memory is a bit foggy but this is every man's dream. I will begin my life in fantasy! Wait...Instead of the protagonist, I reincarnated as one of the girls and must capture the actual protagonist's heart?!
