Two Chiaki f̶a̶n̶s̶e̶r̶v̶i̶c̶e̶ chapters in a row, woah!
Okay I get it, the way the author ship them is different.
DaixChia is your typical youth romance that full with sudden blushing and tsundere action.
DaixSuzu is what I called married couple-like relationship. They'd been as close as slept in the same bed but no shyness or whatnot after that happened, act normal just like they're already a family.
