First all the attention was on Sayama-san.
Rune could handle that. A girl. Just a girl. He knew she was pretty(though he wasn't interested in the slightest) but she'd go away eventually.
Hopefully.
Hoping that one person would go away was easier than hoping a robot that practically stalked Yamato was going to go away.
Chances of that?
Slim to none, leaning toward 'none.'
Rune didn't know how to compete with the boy.
He was so freaking pretty. And he flew. And did a million other things Rune couldn't ever hope to do.

Then Rune had a douji of his own.
Not at all like Ultimo- but he didn't really care.
Maybe- just maybe, Rune could get rid of Ultimo.
Jealous would help. He had to.
--
Rune's dreams consisted of Yamato on good nights, and Ultimo as cold and dead as he had been when he first appeared on better nights.
On the bad nights, Rune dreamed of Yamato crying over a dead, soulless Ultimo.
He always woke up, cold and upset. Jealous did a sort of comforting in feeding the hate of Ultimo.
It was okay to think about him dead.
Completely okay. The little shit could die.
Lay cold and dead in the dirt, eyes dull and lifeless, body ripped apart.
Rune slept dreamless after that.
--
In all the years Rune had known Yamato, and all the years that Rune had liked Yamato, he never once considered confessing.
The moment it crossed his mind, he knew it was pointless.
It wasn't like Yamato was going to hate him or anything- it was the fact that he would say he only loved Rune as a best friend.
And that he loved Sayama-san.
That was before Ultimo though.
Now chances were that he would get, "You're my best friend, Rune." a pause and "I love someone else. It's always been that way and always will be."
The moment that thought filled his mind, he completely gave into Jealous' ideas and plans and completed the vow.
Rune broke a little.
It didn't hurt to think about anymore.
It just pissed him off.
