Couldn't get the idea of this out of my head so I decided to write it. I actually kind of really like it even though my writing style could use some work.

Masaomi dyes his hair back to brown in the winter, after the yellow scarves and the blue squares and the dollars cease to exist. He and Mikado have started trying to patch up their friendship, promising to no longer hide things from each other and deciding that they both need to return to school. After he breaks up with Saki, he dyes his hair to erase the last bit of the yellow scarves that still clings to him along with buying a messenger bag that isn't yellow. He burns everything in his closet that's yellow. He knows that Mikado is doing the same thing with everything that's blue.
The next day at school, he's the last one to arrive on the roof for lunch. He gives both Anri and Mikado a moment to realize that something about him is different before he plops down on the bench next to Mikado and digs into his lunch. The way Mikado's eyes linger on his hair for a moment makes Masaomi smile into his food. He doesn't have to explain, he knows Mikado is smart enough to understand why he did it.
After school, the three of them walk home together again in a way that they haven't for months. When he looks in the mirror after he gets home, he can't help letting out a sigh of relief when he realizes that he's finally starting to feel like himself again.
Months later when his friendship with Mikado is stronger than it ever was before, he knows he's not the only one who notices when Mikado isn't in love with Anri anymore, but he is the first one who did. Two weeks after he notices it, Anri comes up to him when Mikado isn't around and asks him if she's just imagining it or if Mikado really isn't interested in her anymore. Masaomi tells her the truth and she smiles at him with a look on her face that can only be described as relief. They both know she never would of been able to love him like he had loved her.
After that, he lets himself fall for Mikado the way he's been stopping himself from for weeks.
They hang out every day after school, sometimes with Anri but mostly without her. She's usually with Celty and Shinra lately anyways so it doesn't bother her. They all know she's still an important part of their trio.
The first time Masaomi and Mikado kiss it's after a long session of video games at Mikado's apartment. They're laying on Mikado's floor in a comfortable silence when Mikado whispers his name and when Masaomi turns his head to ask whats up, he feels the press of soft lips on his own. Although Mikado's gotten a bit braver since everything happened, he still stares at Masaomi with a look of fear on his face after he pulls away. When Masaomi tangles their fingers together and smiles at him, that look of fear disappears in an instant.
The next day at school when they're even more glued to each other than usual, Anri tells them with a smile that she saw this coming.
Masaomi wishes that life could always be like this, Mikado's hand in his and Anri always at their side.
