Delivery theme? What do you mean?
As in the concept of "package delivery service gone wrong turning into a sex situation"? Or "delivering oneself to others to have sex" 'cause they have the "Dick Delivery" (宅配ちんこ / Code starts with
THT) series if you mean that.
I don't think they've wasted
Masaya (雅哉) at all
. As matter of fact, he got that
Golden Boy treatment for quite some time, getting a lot of projects & promotions more than some others. And he even got the
Colors series which up until now has only been given to him &
Shoei (庄衛) so far, as well as the OF deal from the studio replacing
Hiroto (宏翔). If anything he has been following the usual HUNK-Ch career course faster than others, it's just that he stopped right before he could give us a
Virtual Date entry & that's when he just stopped making new stuffs. But he didn't outright quit until the recent announcement, so he must've been indeed busy
. It's sad, but yeah.
