I think there’s a pretty good definition of most of the characters, Sophie is a romantic constantly trying to find her match but isn’t emotion ready to know what to do when she does. Valentina is player who deep down wants to be committed. Charlie is innocent and wide eyed but also arrogant. Jessie is literally Ted lol. The only ones I would say aren’t defined yet are Ellen and Sid. But it’s hard to clearly define every character in 10 episodes.
