One. Late For School?!

From Korea to Japan, Miku Hatsune has moved back into her home-country. She's been there for about a month, preparing for the upcoming school year. One day, her childhood friend (and her old singing partner I guess..), Kaito Shion, has been running an ice cream stand for a while now. Is Kaito going to offer Miku a leek-flavored ice cream (if there is one) and sing with her, or no?
