Yes, the sandbar scene where Makani hugs someone changes based on what ending you picked. So she'll hug Riu in his romantic ending, Vane in Vane's ending, and so on, and then there's a slightly different version of the scene for the friendship ending too that includes all three of them.
Well it's too bad you don't want to see the rest, but I understand. Sometimes when I'm playing a VN and get a favorite pair/ending, it's hard for anything else to measure up. So nothing wrong with ending on a high note :) And I'm glad the transition between friendship and romantic interest felt natural. Thanks again for playing!
