This is such a cute story line .. I rarely came across a manga that is just dedicated to having a father-daugher relationship as it's core. 
 The story is so touching even if it is simple. You can see how dedicated Daikichi is to taking on the responsibility of raising Rin; even though he did it on a whim. He proves that he is a man of his word and does whatever it takes to be the responsible person in Rin's life and be able to give her the life that a normal child should need 
 Utter cuteness! Would defiantly continue with this series
