I seem to be one of the only ones, but I love Yuri. He's a total ass but I love how sassy & filthy he is, he's like an assassin darting in with a quick dagger in the back, over & over again. He makes me laugh.
Yuri could to much kinder to Teacher (having a mind blank on his name, sorry), absolutely. I feel that Teacher is so deeply depressed & doesn't really have anyone around him. Yuri is that person who sees Teacher & his downward spiral, & keeps an eye on him in his own way. I think Teacher could easily become invisible in his life & fall further & further into a dark place never to return. So even though Yuri's approach is pretty terrible, he's already vitally important.
Just my thoughts, don't know if i explained it well. Thank you for the update!
I need a spin off story for Jo, not just an extra or two.
