First 2 seasons were fun and a nice watch, but season 3 really kicked up the drama. This series really hits home emotionally for me, and it's a fresh breath of air after a stressful night at work. The characters are interesting and fun, but they surprisingly feel human, too.
Also, can I just say that the level of maturity in this series flat out shocked me? Because it did. There's lots of places you think this series might go but gives a different take (such as, how many times do we see breakups in any show where the people involved are still good people and don't necessarily become volatile towards eachother?)
It's a great show if you want some laughs and feels, with a great English dub (always love to mention when a show has a great dub due to the reputation of dubs).
TLDR; season kicked it up a notch and still remains wholesome
