Edit: it is a great series, but it’s as far from a cozy slice-of-life show as you can get without being a seinen battle series.
Like, things Planetes has that definitely don’t show up in cozy or SOL:
Radiation sickness
Cancer
Suicide
Asphyxiation
Kessler Syndrome
Multiple terrorist attacks
Graft
Constant smoking
Hijackings
Frame-ups
Spaceships as WMDs
Hachi’s dad
Just to name a few.
Further edit: are you thinking of Space Brothers instead?
It’s… It’s so not.
