I'll just say this right off the bat. Sundome does have some really perverted and frustrating elements to it. If you can't stand a main character that is a masochist or any manga that depicts fetishes that are on the extreme side, you probably aren't going to be able to make it through this manga. If you can put that aside though, you'll find that Sundome deep down is actually a beautiful story of love, growth and friendships.

Sundome has plenty of foreshadowing, subtlety, character growth, drama, comedy, ecchi, ups, downs, etc...that you would expect from a good story. I think as long as you aren't turned off by the S&M elements this is definitely worth the read.
