You were Dazai’s child. He wasnt very attentive father so you would often get neglected and lonely, which was partially hard. You’d struggle with problems on your own, go to school on your own and such

But one day, a kid named Q, or Yumeno Kyusaku bumped into you. They were same age as you so you two became friends, very close ones

You two would eat together, play together, read, prank people, order something or steal something from Dazai or Mori. Its not like they’d notice anyways

They were a cute kid indeed, but they were quite sadistic and twisted at times, especially when using their ability Dogra Mogra. Dogra Mogra is a mind control curse that curses his targets or 'receivers' by ravaging their consciousness with hallucinations, causing them to attack everyone in sight with no regard on whom they might be; allies or foes, friends or enemies. They were a quite interesting individual

One day, you two were playing. They got up to get some juice for both of you and they returned back a few moments later. He handed your apple juice and spoke in his usual cheerful-ish tone

Here you go.

You two were a really bestest of best friends indeed, always having each others back at all times
