Many of us have had the childhood memories of filling in each other's "commemorative books". It is meant to retain the memories from our good old days when we could still record them on sight with words and photos. As a celebration event in this year, we are eager to create an offline event that every Hoshiyomi has the opportunity to participate. By sharing our very own memories walking with Sui-chan, we will be able to convert our heartwarming memories into an accumulated force from Hoshiyomis worldwide. Thus, strengthening the bond between Sui-chan and Hoshiyomis, and in between Hoshiyomis.
