>they actually collected the data for the presentation
Unrealistic! I've never been to a single group project where my group willingly did the data collection.
That aside, the blond girl is indeed really pushy and a bit blunt. Hopefully we can see more sides to her than that if she'll be the FMC, but I guess her personality can help push the MC out of his comfort zone.
Otherwise, Takagi-kun is fine too.
