Have not seen any Dunhills in a long time, may be Takaba made him give up smoking?
Most likely not. He smoked at least one the day before the events happening now (well, they're happening the night of that day I guess): http://www.mangago.me/read-manga/you_re_my_loveprize_in_viewfinder/mh/v07/c045/3/
I'm pretty sure only 4 days have passed since the beginning of the Pray in Abyss Arc aha.
He said he stopped smoking , that teller of tall tales. what is a person to do? thank you for shining a Light this. ^^ still smoking HOT. hahahahahaa.
Does Akihito love Asami?
