"Hey, Osamu. Did you take a shower today? Your hair is fluffier than usual." That's how it started. That one simple comment from Chuuya was enough to make Dazai stop in his tracks. What?? He hasn't had the time to shower for a few days - currently in the process of moving in with his fiance and the changes to his routine, causing his depression to worsen for the time being.
Excusing himself to the bathroom, he looks in the mirror to find that, yes, his hair is, indeed, fluffier. Pausing to think, Dazai freezes. It's a full moon tonight. He had completely forgotten with all of the stress of moving in!
Here's the thing. Dazai is a werewolf. That transforms to full wolf on a full moon. And Chuuya doesn't know that. Checking the time, it's seven in the evening, meaning the sun is probably setting. No wonder his hair is thicker! God, there's no time to get out of the house, nor could he even do so without raising suspicion. What is he going to do??
A few hours later, Chuuya was sitting on the couch with a sigh. Falling asleep at night - especially on a full moon - was a struggle, considering the fact that he's a nocturnal being. A vampire. Not that Dazai knows. Full moons don't really affect vampires thankfully, meaning it's very easy to keep from the brunette.
A little bit ago, Dazai excused himself to his personal bedroom to sleep early. They got a two bedroom apartment for privacy, after all. Chuuya was a little worried, but didn't question him. That is... until he heard bones cracking. What the hell?
He knocks on Dazai's door and was met with growls. Worried about his fiance, Chuuya opened the door and was immediately jumped by a giant, fluffy brown wolf. It was too big to be a normal wolf - this was a werewolf. And Chuuya recognizes this scent. This is Dazai.
Suddenly, a lot of things make sense. Sighing, Chuuya's eyes go red as he speaks, "Osamu," He starts, "Come back to yourself, baby." He says calmly, using his powers to successfully get through to the wolf and breaking through the moon's spell.
