The comments are all over the board on this one, aren't they? Here's my take:
First, the "H-training" in this is pretty light compared to what you might be thinking it is. There's a bit of tying, use of a collar and leash, and a threesome, but that's it. They show some other toys, but those aren't used (that would've pushed it into true S&M).
I like the fact that the top (what most would call uke) doesn't just roll over and do whatever the bottom wants - he has a mind of his own and he's not afraid to be in control. In fact, he likes to be in control and never thought he'd find an adult willing to accommodate his every whim. But he doesn't want to spring his tendencies on the adult all at once, so he hides his nature and shows what he likes over time.
But it never goes into true S&M, and it isn't really intended to be psychological yaoi. I do like how the seme's and uke's mentalities play into each other's hands, but I wouldn't really call that psychological. If you read the "story" with that understanding, it probably won't be as disappointing as it was to some.
I thought the sex scenes were well drawn, and I like Honjou-sensei's art. Overall, I liked the story because the uke isn't a pushover. I wouldn't call it a cliche story, for sure. I wish there were more stories like this one.
As for the one-shot, Happy Boy, there are some vibrators and one scene of S that you can gloss over. Otherwise, it's not too bad either. It's a cute short story, though fairly cliche, of male prostitute falling in love with a client.
