Here are some of my favorites. Some are not comedy and some are not romance though:
- Bocchi the Rock! (Comedy / Music / Slice of Life)
- My Teen Romantic Comedy SNAFU (Drama / Romance / Slice of Life)
- Rascal Does Not Dream of Bunny Girl Senpai (Drama / Mystery / Romance)
Note: There is also a movie that I highly recommend to watch if you like the series. A second movie was recently released as well but I haven't seen it. - Violet Evergarden (Drama / Fantasy / Slice of Life)
