Rain Bastion's Links
Although Rain would never admit it, he secretly has a huge crush on Dash. He doesn't want to ruin their friendship like he did with Dia, however, so he doesn't bring it up and never peruses a relationship.
Despite this, Dash means EVERYTHING to him and without Dash, Rain would have fallen to pieces when Dia broke his heart a few years ago. He is very thankful for Dash and would do anything for him.
To Dash, Rain is the most important person in his entire life. None of his other 'friends' could ever match up to how close he and Rain are... Although they don't have a lot in common, he would rather spend time with Rain than do anything else.
Deep down, Dash loves Rain as more than a friend, but he hasn't admitted that yet. He sees Rain as an irreplaceable part of his life and because of his own naivety, he doesn't realize that both of them want to be more than just friends.
