not really i mean he more fell in love with a sad situation and pretty face he wanted to help, he wasnt going to commit suicide for her really but because of the debt he got himself into over her. It's not like they got personal, or anything and after almost dying and waking up in that situation i think he had too many other things to preoccupy his mind with
I think the manga is just leaping through time really fast, with out the reader noticing...without any notes like "half a year later" or something...
Am I the only one who can't get over how quickly he recovered from being swindled by the women he loved. He was willing to do anything for her, he was even about to commit suicide....
