Momo e no Tegami, Ookami Kodomo no Ame to Yuki Recommendations
Both are great slice of life stories with supernatural/fantasy twist,
in both main character has to deal with the loss of someone and has to change her way of living to move forward, both have very good mix of drama & cute moments.
Both have somehow peaceful overall feeling, also the countryside setting is similar. And of course, both are worth watching!
