Magical Explorer: Reborn as a Side Character in a Fantasy Dating Sim

There's a legendary Bishoujo Game that has become popular among Japanese gentlemen. Its name is "Magical★Explorer" or Magiero for short. The game's protagonist has a cheat-like power with 12 different beautiful heroines to flirt with, including additional 12 heroines from the DLC, a harem of 24 beauties. I have become that protagonist...! Not! Instead, I have become the third-wheel character who always laughing like an idiot next to him. There's no heroine that would lay their eyes on me.

But now I couldn't care less about the protagonist and his heroines. Why? Because I discovered magic. While I was using it, I have become interested in it. I want to master it. I want to become the strongest. Thus I have decided. I would abandon half my role as a protagonist's friend to train my magic and then I would beat the hell out of that cheat who can solo the Demon King. I was training with that thought in mind, but somehow I keep getting closer to the heroines and furthermore, I don't know why I keep encounter events like I am some Eroge's protagonist.
