Wow, this was such a wonderful surprise! I liked how their relationship evolved to include romantic love and sex, but while not forgetting the bond they forged while Akito was growing up and Yuichiro raised him. Someone would think this resembles incest too much, but in my opinion the author was very good in handling the subject: the fact that the pursuer is the 'son' removes the disturbing element that is often linked to incest, the idea that the younger partner is taken advantage of. In this manga, if anyone is being taken advantage of, it's definitely Yuichiro, who doesn't seem to understand what is happening for the first part of the story (which is hilarious).The art is very good and the sex scenes very hot, so this manga is definitely recommended!
