What are the titles of the piano instrumental themes/soundtracks from the anime "Boys Be"?

I'm interested in knowing the titles and artists of 3 piano instrumentals in the anime "Boys Be". All of them were played on the 1st episode of the series. 1. The first one played when Chiharu and Kyoichi ran thru an allée of Sakura trees on the way to school because they are almost late for school. 2. The second one and also my favorite was played during flashback scene of Chiharu and Kyoichi's child hood, when Kyoichi was in his room browsing through his photo album. 3. The third track was played just before the 1st episode ends when Kyoichi and Chiharu watched the Cherry blossoms at night. I have browsed thru wikipedia and the right stuff for the titles of these tracks but i haven't found any. Thanks for your answers in advance. :)
