Give it a chance, if you liked other works of author. At first story was a bit odd and maybe unnatural. I was kinda disappointed, because I have read Sugaru Miaki's "Three days of happiness" and it was absolute masterpiece to me. But later on it builds up on you starts giving the similar vibe as "TDH"/"How i sold my lifespan...". Touches some philosophical questions and may inspire you to seek something special even when life isn't going the best way. As do main characters of this manga by making each other to desire living. Artstyle is gorgeous, as other works of the artist. Characters somewhat realistic but notyet developed.
It is sad that project was put on hiatus, but there is the source novel available.
