>>9487497>>9486162Yeah, the full context is split over several streams, but Marine was feeling conflicted after Coco's graduation, had impulsive thoughts about graduating as well and didn't sleep the night of the graduation. She messaged Kanata early morning (who also didn't sleep) that she didn't manage to sleep and Kanata invited her to the house where they basically talked, played games and slept. This is also where Kanata (and a few other members iirc) calmed her down from her impulsive thoughts.
It's pretty clear for the regular viewers that they value each other a lot and they're very close, hence why they don't mind being rough with each other but from their stories its easy to see how much they care for each other.
