The origin of Yotsuba, I love the bits and pieces of backstory we get throughout the series. Cuz it doesn't matter what the circumstances of her birth was like, Koiwai is her dad.
I'm genuinely intrigued in Yotsuba's backstory. I never thought this would be so interesting... And thank fuck the assholes at reddit who have spoiled so many jokes of this series didn't spoil this for me 👍
