Someone pls let me know

I haven't read this story yet and the art looks amazing but I'm a bit hesitant to since I heard that ML has a pink haired ex and I'm worried ML is going to be hung up on his ex and treat MC like trash?

Can someone verify if this is true or not? Like what was the relationship like between pink hair and ML and how does ML view his ex? Cuz if he's like those typical jerk ML from others stories I read I don't want to waste my time, please and thank you.
