SWWEEET is a romance/drama manga with some disturbing 'erotic' scenes in it.
It starts out with the protagonist talking to his reflection in the mirror.

His reflection is actually his lost twin brother, who reappeared in the mirror after being missing for many years.
They are having a discussion about whether the protagonist should save their childhood friend (a girl), whose currently bullied severely by her classmates.

After scrapping his balls together, the main character steps in to stop the bullying of his childhood friend. But the rescue isn’t going as he (romantically) planned it to be and things get out of hand.

Well… stuff happens here and there.. ‘drama drama’ .. blah blah..
But I won’t say anything about it, cuz it would spoil things for you as a reader.

Anyways what I liked about SWWEEET the most was the ‘sweet’ character art :o.
Especially facial expressions of the girly childhood friend were drawn very well during different encounters in the manga.

Aside from the art, I liked the extreme moments in the beginning.
And how the mangaka didn’t ‘beat around the bush’, whenever things were about to get ‘slightly’ erotic.
The only thing I can bitch about is how complications got resolved pretty easily nearing the ending of the story.

In short … if you’re looking for romance/drama manga, that gets a little extreme/erotic with an occasional ‘rape’. Then SWWEEET might be an interesting read for you.
