>>108034867Marine and Kanata used to be joined at the hip, being there for one another during tough times in the past
At some point, possibly aligned with when Ao got close with Marine, Kanata and Marine stopped doing things together
For most of the month since her graduation announcement, Marine has largely avoided discussing the grad or talking with Kanata
At 11th hour she finally calls into totsu for a few minutes and amongst other things, admits that she wasn't there for Kanata like she could have been during these incredibly tough times for her
TLDR
Are they still friends? Maybe, probably
Did they grow apart? Absolutely
Is Ao to blame? Timing makes it seem likely
