While wondering what to do for Rinko's birthday on June 15, Takeo learns from his mother that he'll become a big brother come January. Claiming he has something to do that day, Makoto instead helps Takeo with his plans for Rinko's birthday, becoming quite amused by his own memories his suggestions bring up. As Takeo takes on a part-time job at a café to earn money for a present for Rinko, he learns that Makoto's father had been hospitalized and is to undergo surgery on June 15. As Makoto urges Takeo not to abandon his plans with Rinko to accompany him, Takeo decides to respect his wishes.
