K-On!, Kokoro Connect Recommendations
-Both anime's animation look really similar because they are created by the same character designer (Yukiko Horiguchi) and they both surround school life, comedy, drama, slice of life, as the story focuses on their daily life in their respective clubs.
Only difference is that K-ON's story focuses on comedy and the daily life of a group of girls, while Kokoro Connect focuses on drama/romance.
The animation looked a lot like K-on although I think they have different producers/animators.
Although music is not a major theme in Kokoro Connect, both series has some parallel similarities that are drawn together:
*Both series has similar character designs of the main characters with a similar setting taking place at a school.
*Both series has a slice of life theme to it involving the main characters
*Both series has comedy and drama that are executed well and not forced
*Both series details the relationship between the characters and how they progress through friendship (romance in Kokoro Connect among some of the cast characters)
Similar character design, but one is moe tea time, one is romance. Tea time include play music, romance include kissing.
Both are similar involving school clubs and activity while K-On is more focus on Slice of Life and the Comedy, Kokoro Connect has more romance and drama involved.
