Hard Triangle
2.5 stars. Story 5 was really sweet - I really liked it, (would have given it 3.5 stars). Story 4 was intense and not bad. Story 3 could have been good, but it was clumsily executed. I didn't like the first 2 stories. I didn't like the art at all! The pointy ears and nails made them look like pixies or demons or something lol!
Kuse ni Narisou
The first story was sweet. The second was interesting and messed up (in a good way). The 2 were completely different.
Mask
I really liked this, (especially the first of the 2 stories, although the murderers all creeped me out). It had everything: romance, humour, sex, action, drama, mystery... I enjoyed all of these elements, but I mainly found it super sweet. I would definitely reread it. Oh yeah, and I liked the historical settings, too.
Sono Ude De Boku O Daite
Roses of the Rhine
The first story was entertaining in parts, but dragged on for too long, with them only having sex right at the end - It felt more like a shounen ai. The second story was ok but not brilliant - It had a good basic premise, but which was insufficiently developed, due to the story's brevity. They were both relatively entertaining, though.
Calling (MIYAMOTO Kano)
Afterwards, read the dj, (also by Miyamoto).
Kyou, Hana No Gotoshi
Really sweet and fluffy, but completely unrealistic. Love the art style. The guys are all gorgeous, plus there's a beautiful kitty to boot.
