Kowarekake No Omocha
The "Toy" series ended up being rather depressing. The uke was pretty much being physically and emotionally abused - too much Stockholm Syndrome and not enough feels. The childhood rival/friends/kidnapping story was funny.
Hitomi Wa Umi No Iro
Okay, besides the initial series of stories, (which included the entire trope library - foreign prince, rape, kidnapping, Stockholm Syndrome, fated partners, family interference, etc.) which were ho-hum, the second series about the food critic was more enjoyably funny.
So Cute?
The author really knows how to convey emotions well. The samurai story was sweetly sad, but the last little omake makes up for it.
Trip
Sex was less than smutty. The salaryman in the first stories was rather creepy.
Touch Me Again
Beautiful sad stories of love in all it's painful awkwardness.
Kare No Niwa Ni Saku Hana
The first story is an absolute heartbreaker. Other stories are sad, twisted or moody. Still and all, a good read.
