Are you going for a pair with the Mc and Chara if that is the case, I would find it wonderful, I only saw 1 pair of chard through my 1200 hours of reading so I think it would be original.
Something like that. I’m not sure yet because the pair for the Protagonist is not yet set in my mind.
But the character who is winning agaist all the others easily so far is Chara. By chapter 15 I must have decided the pair.
