It's been over a year since Rin moved in with Daikichi and he still has no idea what he's doing, but we're learning that with friends like Kouki's Mom, Daikichi has begun to subconsciously build a good support system for his little family.
In this installment of Bunny Drop Daikichi has no idea how to react when his cousin and her daughter show up at his door step having just run out on her husband and his family. He spends a good portion of the chapter trying to understand why Haruko felt the need to leave so abruptly and although it's never fully explained, we can deduct that her husband wasn't spending enough time at home and she was lonely. We also get to see Daikichi panic when he run's into Kouki's mom in the supermarket while he's with his cousin, Haruko. I think they would make an adorable couple.
We then see Daikichi turn to Kouki's mom (who's named Nitani by the way) for help when Rin get's a fever. Some times I have to say that I want to shake Daikichi, Rin has been with his for over a year and he still struggles to care for her, it was nice to see Daikichi and Nitani working together though.
Later in the book we see Daikichi meet a few more of the dad's from Rin's class and we get to watch them interact. It's interesting to read about because the only other dad's we've seen mentioned in the book were the other men that he worked with, but because all of the children are classmates, we get to see a bit more interaction.
I'm still routing for Daikichi to get it together, but I have a feeling that Rin will always be a bit more mature that he is, and I'm okay with that.
