Hachimitsu to Clover, Hanasaku Iroha Recommendations
Both are about finding your place in the world and the process of becoming an adult.
They both have something really serious going on, yet they seem to always find the happier, if not brighter things within it. Also, the same singer for their OP.
Both have same the same atmosphere to them. Both have the recurring theme of adolescence and tackling life's hard choices. Both main characters (Takemoto and Ohana) are undecided about their future and do their best to help others.
They also feature insert songs that fit the mood of what is happening during the show. IMO Hanasaku Iroha is a Honey and Clover more targeted towards teenagers, rather than older viewers or college students.
Both anime have great character, story is very original and it tell us about how to make important choices in our life, how hard life can be, and the most important it has the same feel and atmosphere.
