>>58600247In this chart, lines with arrows generally mean the relationship is one-way.
For example, the darker green lines are for "mentor+trainee" relationships, so green arrows show which character is the mentor and which is the trainee, and that the dynamic can't be reversed. So Green (boy) is a mentor to Yellow, but Yellow is not a mentor to Green.
Unbroken lines without arrows represent a mutual relationship that equally goes both ways. For example the darker blue lines represent friendship. So Crystal is mutual friends with Eusine. She's also in a this weird pie chart circle with Gold and Silver with the same color blue outlines, meaning the Johto Dexholders are all mutual friends with each other.
Now again the bright red lines represent "love" in a romantic sense. Nearly all the red lines in the chart are arrows, so they all represent one-sided crushes. So Leo is romantically interested in Hugh's sister, but she doesn't feel the same way. Similarly both Yellow and Misty have crushes on Red, but he doesn't reciprocate their feelings. The only unbroken red line in the chart is the border connecting Ruby and Sapphire, representing their mutual romantic feelings for each other.
