Raku was asked by Kosaki to help out at their family's sweets shop. While in the line of work, a strong typhoon forces Raku to stay at Kosaki's house for the time being. While under awkward silence at first, the pair eventually holds a proper conversation until the typhoon subsided — allowing Raku to head home safely — much to Raku's discontent. Nonetheless, Raku was able to exchange e-mail addresses with Kosaki as the latter feels proud of the progress she made with Raku.
