First up, both are relaxing slice of life show with a little comedy. The impression depicted by both gave the sense of a smooth progression without much climax that would get your heart beating faster than usual. But that is also why both shows are nice.
Second, both of the shows have excellent theme songs - I'm sure many would like it as well.
Now, if you are looking for a show for you to sit back, relax and watch, or after watching numerous action/horror show, then you pick this up.
Both of these are adapted from my favorite mangas that I'm obsessed with, and therefor both my top favorite animes so I may be a little biased. However both of these shows are cute and heartwarming. Helping put a smile on your face with the cute characters, comedy scenes and the general adorableness. Both feature a cute, unique cast of characters. Following a girl new to town (Moeta and Hana- who both are themed pink, are shy and love cute things) who easily becomes friends with three girls. Including the energetic and outgoing Koizuka and Tama. besides the main four friends, there is a cute cast of background characters. Cute comedy slice of life mangas following high school students. read more
They have 4 main characters that hang out and mostly do normal activities, presenting several moe-ness in both. Hana Ichinose and Akari Akaza are the "main characters" who are a bit insecure about their place in their respective group and also have short pinkish hair.
Slow Start has some implied shoujo ai, while Yuru Yuri presents an overt shoujo ai.
Both feature cute girls doing cute things, and are very soothing to watch.
If loveable cliched characters and adorable shenanigans are your type of thing, sit back and enjoy. They'll both surely put a smile on your face.
Slice-of-life comedy filled relaxing anime. Doing everyday activities with friends like what they would write, "cute girl doing cute things".
While Hinako Note was doing things related to Drama, Slow Start I think was more general....
Slow Start and One Room are both shows about cute girls’ daily lives in a very similar art style. While Slow Start surrounds the lives of high school aged friends in and out of school, One Room focuses on three different romantic relationships taking place outside of a school setting. One Room also utilizes a first person perspective while Slow Start uses the typical first person perspective.
I'm kind of cheating here, since this recommendation is pretty low effort. Well, for starters, both Mitsuboshi Colors and Slow Start are from the winter 2018 season. Both anime involve a group of cute girls just going around doing their fun little adventures. Slow Start takes place in high school, and the girls meet the main character on their first day of school, and than start hanging out together, performing their cute antics. Mitsuboshi Colors involves 3 young girls having their own club house and having fun playing their childish detective games. Both shows are in the fan genre, "cute girls doing cute things", and they're quite enjoyable to watch. Both anime will give you some simple fun entertainment to make you laugh a little, although Colors is better. Slow Start doesn't have as much charm. read more
K-On and Slow Start are both works about friend's influence over one's own life, and use their directing and writing for the primary purpose of making the viewer feel the warmth and purity of the protagonist's bonds.
The characterization in K-On is much more subtle and nuanced than Slow Start, which is fairly overt in every element; from the moment the cheery opening plays, with its bright, pastel visuals, the show's intentions are obvious, however, this does not prevent, and in fact, assists in, conveying strong themes and emotions.
Both are very satisfying to watch as a "cute girl doing cute things" show.
Both series star a group of girls with very different personalities who meet each other on their first day of school and become friends.
In both cases, the protagonist has a special trait that negatively affects their otherwise mundane life. In the case of Anne Happy it is An's luck and in Slow Start, it is Hana's later than usual high school enrollment.
The art style of this anime is very similar to Anne Happy
