This is a longer one but I still go back to it sometimes because it's a rare example of women actually trying to communicate.
Subaru and Marine were uncomfortable around each other for years, to the point where they felt they had absolutely zero chemistry. No matter how many times they collabed and the fans said they loved it, neither of them felt like they vibed well with the other. But they took the time to sit down, figure out why they felt that way and actually tried to work it out. Then they solved everything in the most anime way possible: with a hug.
It was great to see that after this stream, they hung out offline more and genuinely enjoyed each other's company.
