I've seen some comments around regarding the romance so I thought I would ask for more precise information. For those that already read everything available, on a scale of 0 to 100%, how much does the romance take part in the story? Is it really more of an occasional hinted thing you see once every 30 chapters? Or is it more connected to the core of the story?
Also, I just saw that there's an anime available, so if I decide to go for that first which is the manga chapter that continues the story?
