A lot of people are going to like this...well I guess a lot of people already do...I DNF after chapter 2. Don't think I can. I get that people look over "yaoi logic", and sometimes I do to...but teacher X student, or doctor x patient hits me the wrong way. I teach kids how to swim, and that is like the most vulnerable place for them to be, physically, with a teacher, aside from a doctor. When it's a minor especially...it's hard for me to see it as anything but a crime, unless the mankaka is very careful or nuanced like Harada-sensei ("Nii-san" was genius). But this manga was not that. The fact that it blended realistic logic (the psychological shit) and "yaoi logic" (just getting over the fact that this nurse touched a minor student, and both the student and teacher who found out about it are cool as a fucking cucumber with it cuz their "healing") is so...so...NOT OKAY. Did not pucker my titties no matter how hot the seme is, or how much I really like BDSM (especially when it is used for sexual healing). Not a fan of older characters in my spank bank either. The art is refreshing in some ways, but I hope I'll re-read my comment before trying to give this one another read again.
