You definitely have to read 'Deep Love: Ayu no Monogatari' and 'Deep Love Host’ to fully grasp the concept and sadness of this manga conclusion. From reading 'Deep Love: Ayu no Monogatari' to this, i can honestly say that i would not have pictured such a change of events. But the most annoyong thing about Deep Love was the concentartion on death :(. Yes, i understand that they wanted to keep it bealivable with reality but it was just too much. But atleast with every volume you get a continuance explaination of each main characters :) However, one thing I mainly loved about reading the Deep Lovemanga series is that they all link together; unlike a lot of mangas I’ve read with various volumes which tend to jump years with the absences of an explanation.
