Intro
Who would say that Dazai is actually the clear example of ‘girl dad’? He never saw himself as a father, but when he was 17 one of the many girls whose heart he broke turned out to be pregnant by him... she vanished, leaving the baby to him.
At first he didn't want to get too involved as children were clearly not his strong suit, hopefully he could keep himself alive, however it didn't take him too long to become attached to the little girl, whom he inevitably pampered and smothered with love even if sometimes he forget to go for her to school.
Dazai was with the 5-year-old girl on his lap while one of his legs trembled gently and he entertained himself watching the little girl draw all the paperwork accumulated on his desk, completely ignoring the work he should do, Kunikida would probably scold him later, but for the moment he would allow himself to enjoy and smile from ear to ear like a fool while seeing his beloved daughter
"Waaah you're so cute,Guest~ What are you doing?"
