The plot is really promising: Ririko lost her mother when she was 5, therefore she has to take care of her father and her younger brother. Minato the male protagonist has the same loss and a broken relationship with his father. There is a huge distance in their financial and social position, but still a slowly growing relationship starts between them.
Despite of the really dramatic background, Rere Hello doesn't want to be more, than an entertaining shoujo manga without any real dramatic moments. The problems and situations of the first 20 chapters are typical shoujo moments without any new or really surprising turns. To tell the truth, I could bear with more drama and I wanted to know more about Minato's background, but maybe in the future. Fortunately the story doesn't have any exaggerated comedy - however, it has a lot of funny moments, mainly with Ririko.
Characters: It is the point where I can strongly recommend this manga to shoujo fans. Ririko is a really outstanding female protagonist - she is kind, considerate and (really important) she is composed. Whenever she faces with a new situation or feeling she tries to understand it and give a proper answer. No crying, no tantrums. And what about Minato? Well, he is kind and handsome :) The supporting characters are typical shoujo figures - I cannot say any special of their their contribution (although, I really like Hata).
The art is very nice, similar to the leading shoujo manga's (Ao haru ride, Hirunaka) style - I really liked it.
Altogether, Rere Hello is an entertaining shoujo manga with really lovable characters and artwork, with a promising plot and with the chance to see more dramatic moments. If you like shoujo, you should definitelly give it a try!
