Rereading this for the nth time, I just noticed Ousuke prob has a thing for Asa, who has a thing for her teacher.

There've been a few WNs and LNs of the sort running for quite some time (years, i mean), due to their nature as adaptations I think it's more that they've started picking up steam rather than them being a new fangled thing.
