Hachimitsu Ouji Wa Shitsuji Ni Madou
Pretty art, but hilariously bad dialogue and blehh hackneyed plot. Example, "His skin is like it's been bathed in syrup" ... not sexy, unless you have a thing for attracting bees. Things happen which are meant to rachet up the UST, but when the butler finally snaps and molests the young master, it falls flat badly and completely lacks sizzle, mostly because there is no UST when it's so obviously building up to that moment. Also, why does such an accomplished and interesting butler admire such a dull, dough-head of a young master anyway? There's nothing there to entice anyone, apart from big eyes and frills (which butler can find anywhere.) No juice award for lack of smexy.

Shitsuji Kyoushi no Renai Jugyou
A silly comedy about a butler-turned-teacher who tames a spoiled young master-delinquent and his coterie of other young master-delinquents at a fancy-schmancy private school with blackmail, public humiliation and spankings. Ride 'em cowboy!
Koi no Hajime
A young master strives for personal independence and works at a restaurant, throwing a curveball into the schedule of the coworker asked to oversee his progress. The restaurant manager has a thing for the butler who looks after him. Gentle stories without much conflict.
