I just realised Yanda is to Yotsuba like what I am to my 7yo cousin
He teases her and likes to play with her but she doesn't like him partly because of the teasing and partly for no reason at all so he teases her more
I suddenly love Yanda now
Yotsuba doesn't like Yanda because he was being a right old shit to her when they first met. Neither probably remember what actually happened, but hey, sometimes all you remember is that you don't like someone
I honestly expected Yanda to finally pull out a Bubble Thing — a sort of fabric loop on a stick that you can use to make bubbles bigger than Yotsuba. The best video I could find is unfortunately a commercial, but I'm not affiliated with them: https://youtu.be/tKG_QdsBkv4
