>>37752355Interacting with someone new to create something new is change and it is growth. If they become friends or not is just a part of that. A one off collab means that they've worked together, had different interactions with that person, gotten to know one another and adapted to do something interesting for you.
That's a development in a relationship, development as a creator and new content for someone to enjoy. All of this is part of the "journey".
If they're not checking up on each other on LINE afterwards and asking how their day has been, that doesn't mean the content made isn't different and interesting. It also doesn't mean that nothing has changed.
Also I object to the music comment, you're gay.
