While it's a bit over the top, I think the feelings that are conveyed in this manga are very natural... you love a person but hate them at the same time cause they hurt you, yet you don't stop loving them... not everyone is strong enough to just end it all!
To me, the uke only acts human. Humans are selfish and do things that make no sense sometimes...
I loved how dramatic/tragic it was, very very well done in aspect of emotion and feeling, I really felt the angst and sadness here. It's a bit on the shallow side sometimes, I'd like it to be longer so that it'd have the time to properly build everything up and end it properly as well. In just one volume, it had a good start and everything but toward the end it did feel rushed, leaving me a bit unsatisfied when it ended!
Nevertheless, I think this is worth reading despite it's flaws, both characters have their faults, big time, but they are so likable! They feel real with their jealousy and flippantcy, much more so than the ever so common 'it's the one big, true, perfect love right away' kinda characters.
It has it's angst and depressive theme, so if you are looking for something light and cheerful, this might not be for you, but anyone looking for something a bit deeper, give it a shot!
