Oh man, I hope it isn't well another man trying to step on my turf, because then he gonna get broken legs. (and neck, and ribs, and spine).Okay, this is the last spoiler/hint I will give.
Let's just say the return of a certain person lead to a somewhat close relationship before to kind off... Cool down. And one of the participants is blaming Fiona for it because apparently that person and Fiona are closer than ever. So that person then does something behind MC's back, nothing that really hurts him, just something that surprises him. The explanation of that person why she has done that will be...Interesting.
