K-On!, Kimi to Boku. Recommendations
everyday life of group of friends
both are good slice-of-life and comedy
First of all, these are great anime I must say.
These anime both involves how they spent their highschool and how they bonded with each other at that time. Kimi to Boku may not be a "musical" anime, but I can tell you right now that K-on and Kimi to Boku have a lot in common.
