Being a kind girl, Ayu offers to help Nina look for her lost item. Nina though seems reluctant to say what the item is that she lost and runs off. On her way home Ayu finds what seems to be a mini-computer underneath the bench she knew Nina to be at earlier that day. After returning the item to Nina, who starts to see Ayu as a very nice person, Nina struggles to decide whether to let Ayu in on the 'big secret' she keeps. In order to see if Ayu is truly nice she starts to follow Ayu around and eventually decides she can trust Ayu.
