I liked this manga much better than it's prequel. Even though the prequel had darker themes, I felt that Before Daylight Love was more mature, and its characters were more sophisticated. I've noticed that the semes in both BDL and After Morning Love are significantly less developed than the ukes. I wonder why the mangaka decided to draw them this way.
I particularly liked Daiki's character. There isn't all that much character development, as this is a fairly short manga, but Daiki comes across as strong, decisive and sure of himself. Life repeatedly goes wrong for him, but he never starts feeling sorry for himself or
complains. He just decides on the best course of action and takes it, without turning everything into a big drama. That being said, he did struggle a little when he thought he was losing his identity, but I found that bit of weakness added roundness to his character.
Rin, the protagonist from After Morning Love, also has several occasions were he shows strength in the face of hardship. But the situations he must deal with are so vastly more traumatic, and his character is so much younger and less mature, that his strength came across as less authentic.
There's no doubt about it though, yakuza yaois are awesome.
