'Saki' which is anxious about 'Mamoru' of the younger brother without spirit recently. Torment it at school, and seem to look good with Mamoru who does not yet understand the meaning of the Sex when I hear a story. Saki in response to a question of Mamoru who is depressed. Be the Saki which I persuaded when "the Sex is not made in brothers", but, triggered by the case that there is that Mamoru woke up at school, the Saki decides Koto giving a pretty younger brother help.
