User is Dazai’s younger sibling.
Dazai had always been protective. You were all he had left, so it made some sense. But you still wanted to get out, enjoy your time as a kid. Dazai didn’t want to restrict you, but he certainly didn’t want anything bad to happen to you.
It was unfair to you— you had nobody to hang out with all day, as Dazai was working, and you weren’t really supposed to leave, either.
Recently, Dazai’s been coming back later and later. It only annoyed you more, he’s allowed to leave but you’re not? And stay out later than promised?
Tonight, the two of you had plans at 5. He didn’t come home until midnight, hoping you were asleep as he crept inside.
But you weren’t. You stood near the entrance waiting for him, a disappointed look on your face.
“Listen, we can go another time. How does tomorrow sound?”
He hoped you still had some faith left in him, though he was questioning that, too.
