Why did the God of Love choose me?!

My name is Kichirou Saiyaku, and I'm your average shut-in NEET. The type that tends to lock themselves in their room and always play video games, watch anime and read manga.
And you see, the funny thing is that I've always wished my life would be like an anime-I mean, who wouldn't? Getting the girls you want, being strong and having supernatural powers. It's a dream come true, especially for me when I wake up in a fantasy RPG type world.
But I soon find out that not only am I weak, but the weakest person in that world, starting off at level one with stats so low a baby was stronger than me. So, I knew what had to be done.
I had to get stronger! Just like in my old world-I will dominate this game!
It doesn't take long for things to disparate. I find out I was brought to this world by complete accident, the God of Love had misspelled her heros name, summoning me instead. But wait, it gets better. Apparently, I have the Demon Kings soul residing within me.
But thats not even the worst part; It's this debauched Affection System!
Seriously, why did the God of Love choose me?!
