Fukujuu no Gakuen
First story (first ~150 pages or so) priest teacher and a student he fell in love with. His atonement is giving his student his body--including submitting to him with it. Second story is a guy who gives up his body to yakuza to pay a debt and help save the house of the son of the man who took him in. Not as good as the priest. REALLY enjoyed the priest one.
Datte Ai ja Nai!?
Enjoyable story with a yakuza loan shark and the guy who owe him money. Two side stories: one with a daycare teacher and an older man who's a father; the other two guys in sales that is TOTAL CRACK with a catheter and it was just... weird. LOL Fun, though. :)
Heart Strings
Good story about a host and yakuza head who falls for him. I like the scene toward the end where the host goes (well, gets kidnapped to) the leader's house to be presented and ends up doing the whole formal bow and accept us thing. Pretty cool. Good story.
Trigger
The one with the prince seemed not-quite-HEA, because I'm not exactly sure where it would go. The rest, however, were nice shorts. A few were yakuza-oriented, one couple meeting up after university, one couple from the office... Pretty simple but good stories.
Sugar Code
Kyou, Hana No Gotoshi
Three stories--first is the yakuza heir and his body guard, second is the company president and the employee he gets to help him break up with a girlfriend (and they end up together), third is the 1st Yakuza heir's friend and the pet store employee he falls in love with.

Oh man, so good. Got me in the heart, but SOOOOOOOO good. Side stories of kid with glasses who ends up with his crush and the other with the father's former lover who was so hurt and lost he tried to hurt the kid he was in love with, but they work it out and get together. The yakuza/tea one, though, definitely pulled my heart out and beat it up before putting it back. So good. Definite reread.
