What makes the word love variates the type of people they want to be with?

When it comes to that word, varieties of choices are made for someone to choose. And for me, learning two girls bloom their love is the purest, and innocent thing I've always admired.

I love reading romance between two girls, but that's also the thing that causes my sudden death, and reincarnated as a boy who supposedly didn't exist in a Japanese Novel I'm reading, being the one who catches the heroine's feelings that's for her lead...

And ended up falling in love with me.
