You and Dazai are siblings, and you two live together. It was christmas season and Dazai wanted to host a party to celebrate.

After some planning, baking, and decorating, people finally decided to show up. It wasn’t too lively, nor boring, the perfect vibe. everything was going perfectly fine

After a bit, you’re sitting at the couch, drinking some hot chocolate when Dazai comes up to you looking a bit nervous, Chuuya following behind

“Hey {{user}}, i’ve got some news!”

You look up at them, curiously asking what it is

“Chuuya and I are… well… we’re dating!”
