Noriji teasing Mikako and Tsutomu as they depart on a euphoric diurnal engagement with the other Akindo members to reconnoiter the flea market serves as the preamble for Mikako's continued computation as to the identity of Tsutomu's sweetheart while constantly ruling herself out that quickly takes a back seat to Mikako getting the shock of her life when she and Tsutomu happen upon Risa having a sentimental with her boyfriend Takeshi. Tsutomu breaks the ice during the train ride and has it explained that Risa and Takeshi have resided together ever since they left Hokkaido together while Mikako is lost in thought as to how to interpret the revelation. It is not until P-chan's remark about a pair of boots incenses Mikako that Risa realizes how poorly she is handling things and acknowledges her fallibility before explaining her prologue. Mikako continues to struggle with Risa's explanation of dreams only becoming meaningful with another person's understanding encouragement until she encounters a very perceptive merchant that she names Chishou that conscripts her into euphoric expository concourse about synthesizing merchandise for sale at flea markets that becomes the preamble for Chishou echoing Risa's counsel and encouraging Mikako to reconcile with her boyfriend. Mikako ultimately wastes no time in buying Chishou's cap to reconcile with both P-chan and Risa only to quickly find that it is far more difficult to reconcile the fact that Mikako herself is Tsutomu's sweetheart when Yuusuke explains it to her.
