I don't want to write a long review about Shiawase Kissa Sanchoume, simply for the reason that I don't need many words to describe it.
Shiawase Kissa Sanchoume is a warm and funny shoujo manga. The romance is very slow, so some readers might get impatient.
The manga has a warm and comforting atmosphere which is caused by the sympathetic characters and a humorous, heartwarming plot.
The art is very nice and fits the manga pretty well.
The characters aren't outstanding, but they don't feel like flat characters and it is hard to hate any of them.
I recommend Shiawase Kissa Sanchoume to everyone, who wants to cheer up or just likes to read warm stories. This goes for both genders.
