I can't remember the last time I read a yaoi featuring a stalker that (sort of?) respects ...

yeah. I normally avoid those with stalker stories because they're commonly used as sexual fodder and the major issue is treated very lightly but this manga brought more consciousness and conscience. It makes us empathize more with him as well, as we see his efforts in managing himself well and that is showing his genuine feelings for the other. It may just be because he isn't a complete gone case yet but it's true it's nice to see this thing now. I'm hoping for a healthy outcome for him, especially.
