This looks to me like a dating app called bumble where, for man/woman matches, the woman is supposed to initiate the conversation.

You can check which song you last saved on Spotify (for example) by just looking at the top song on your liked songs, but the question is just to get to know each other; even a “i don’t remember what song I saved last but I’ve been really interested in [so and so artist] lately” would be a totally sufficient answer.

Because of the extreme evasiveness, elitism and condescending tone of yellow, yellow is supposed to be the annoying one. In my opinion, white just seems to be trying to continue the conversation and encourage yellow to open up about their music tastes to get to know them.

What does ToR stand for? Might be easier to find the subreddit that way.
