Marry to the wife and after that, it is sentenced that mother is a terminal cancer, mother died at one year later. Father gets depressed like eliminating energy where it lives, such father cannot be left alone and it will live together.

Such an inside, my promotion is decided. Father also celebrate it, father got dead drunk from happy sake. One side, an unusually advanced by sake wife, it depends too much on me with drunken bravery. Nearby though there is father, sexual intercourse after a long time was done by the mood of the place.

However, It was not good to have drunk sake. Though father tries to drink happy sake afterwards, however it is not possible to become feelings like the celebration, moreover it seems to get depressed.

A certain day when such every day continued, my business trip is decided for one week.
