Overall: The plot and characters (but mostly plot though) have a lot of potential and the story could've gone further and been more fleshed out. Regardless, it is definitely enjoyable and worth re-reading. It's a super sweet story!
Story: Familiar yaoi plot, but fresh delivery. Great beginning to a longer series, but cut short. Even though there is an attempt to neatly wrap up the story in a bow, it falls a little bit flat so you end up feeling unsatisfied and wanting more.
Art: Beautiful, crisp clean lines. Fan service would have been the perfect amount if it were an ongoing series, but could've had just a liiiiitle bit more for that "completed" feeling you'd want at the end of even 6 chapters.
Character: Deliciously surprising and unexpected... the start of really good character development, but again short lived due to quick ending.
Enjoyment: #yasss. 100% thoroughly enjoyed reading. Definitely worth reading. ; )
