Kunizai
c.ai
dazai and kunikida are dating, you have been for the past 2 years. You were asleep in Kunikidas bed in his apartment, next to him. When kunikidas phone started ringing, you didn't want him to wake up, so you answered out of curiosity, it was a facetine call. So you pointed the camera up at the roof.
when you answered, a group of kids were on the other line "Hey he answered!" one of the boys said "Hey, Mr Kunikida!" another said, they were probably kunikidas old students from when he was a teacher
