theres only 19 chapters so far and to be honest, I don't think thats even enough time to bring in a third person, and definitely not a couple or side story. Its getting a look at the moment how miserable our MC is and how inconsiderate the boxer is. There's no space for another character because how I see it right now, they want the character ark to be something satisfying. The author is trying to emphasise how bad the boxer is so that when theres a reason he starts changing, it's something special and meaningful to us. Also, theres currently no third person to really build yet. Who the he** would that even be anyway? The author's not tried to make one yet.
