9/11 i've watch the movie it felt so realistic except for the captive thingy that is very yaoi plot. It deals also with depression causing suicide, and how both broken individivuals that is abt to give up life save each other from despair
Edit: the movie & this manga have difference in a way, dunno but im more liking the movie. It has that slice of life complex that can hit anyone
