Kokoro Connect covers a lot of really heavy emotions and struggles people have, such as Self Identity, Old wounds, Being honest about yourself, and trusting your friends, and dives into how those struggles shape the relationships with others around them. Even if you can't relate to all the struggles, the characters and writing is strong enough to keep you engaged and caring about what happens.
The pacing is really good; it starts out fairly lighthearted and funny, and slowly progresses into the harder topics and frustrations while still being true to the characters. Sadly, the final arc (14-17) frustrated me because the viewer gets to figure out the problem early on but has to watch the characters flounder for a few episodes, which made me enjoy that story less.
All 5 characters are developed really well; while Taichi is definitely the main Protagonist and seems like a perfect savior at first, each character gets their own hardships revealed and has to overcome these challenges, and Taichi gets some of the same treatment. While the different arcs tend to have one or two characters as the focus, they all still struggle and experience growth in good ways.
