From what I know about Blood Drive so far, this is the current “Who Has A Thing For Satoshi” chart, along with the people that have a thing for the people that have a thing for him.
Wait Miss Yui and the new teacher?
Yui, in her Book of Shadows chapter which takes place a while before the Sachiko Ever After charm, falls for Satoshi by the end of it. and Kuon makes some SERIOUS bedroom eyes at Satoshi while she’s in a hot spring and he’s not, while making conversation with him in chapter 4 of Blood Drive. So hers is slightly speculation.
I wouldn’t say Miss Yui fell for him, he just reminded her of the guy she had a crush on in high school which made her remember a very scary and very personal memory while she was going through her hazy sickness.
While he did remind her of the guy she fell for back in high school who looked VERY similar and had a VERY similar personality to him, after she woke up from the dream and was completely aware of her actions as though she weren’t sick anymore and after she sent him home after having cared for her all day, she said the following:
This implies she’s beginning to fall for him, and she has to remind herself to be careful not to, as relationships between a teacher and their student can end with them getting fired. That may not be what she means about being careful though, however heavily implied it may be.
