Hello. I've circled characters I cannot recognise. The top one looks like を but there is an actual をnext to it and it looks different. Why? The middle one is ゆ in my opinion. But I'm not sure about that. Why does it look different to the usual ゆ? And according to my research the bottom one is ず. But again I have to ask why is there another ずand it doesn't look like that? Thank you all for your answers!
