omg cute... SURE WHY NOT!! sakichi stoically being sandwiched by cute girls makes me laugh. i'll probably jump into that yachi thread too

also he would've been gone doing military stuff for the bulk of dia's high school life, but he would've written letters to his mom in recolle to pass on to dia and yachi!! correspondence was probably hella slow, but sakichi would've been interested in keeping up with their school and family lives... please tell him about your hopes and dreams so that he can encourage you from afar!!

ALSO ALSO he'll have come home pretty recently, so he might still be living at his childhood house with his mom until he can figure out where to move... so they'd still be neighbors?? i'll update you if this changes
