Characters in Order of AppearanceEdit


Eiichiro starts to call Natsu "Nacchan" instead of "Takasaki-san".


When Eiichiro was just started playing tennis, Eiichiro was calling Natsu "Takasaki-san", while at STC, everyone calls Natsu "Nacchan". Yukichi wonders why Eiichiro still calls Natsu "Takasaki-san" instead of "Nacchan" as they look close. Eiichiro feels embarrassed to call her "Nacchan" suddenly.

Before going home, Natsu asks Eiichiro if he will stay at STC a bit longer. Natsu gets surprised when Eiichiro calls her "Nacchan" but she manages to smile and gives her goodbye greetings to Eiichiro.

The next day, Eiichiro calls Natsu "Takasaki-san" again but Natsu ignores him. Eiichiro continues to call Natsu but she keeps on ignoring him. After several calls, Natsu finally responses and complaints about Eiichiro switching on how he will call Natsu. In the end, Eiichiro settles down with "Nacchan" but it might take a while to get used to call her in that nickname at school.
