I've died at least 16 times over from the total moe-ness of this manga...such an amazing read!
I honestly hope they talk more about the pass about his GF i really want to know what his little brother did to make it feel like it was his fault. As it seems, she was terminally ill, so i'm guessing he might have caused him not to be there while she passed or something of the sort. Or got into a really big fight with her, just hope we find out soon and this gets updated super super soon, i need it now lol
