Gekkan Shoujo Nozaki-kun, Yamada-kun to 7-nin no Majo (TV) Recommendations
Both are romcom that's full of trainwrecks and weirdos.
Some point the plot will be an one-sided romance then immediately ignored/destroyed by the other side.
In Gekkan Shoujo the one in love is Chiyo while Yamada is the one in this anime.
Light hearted tracks(slow tempo,not bassy) are used in both anime.
