I would like to point out this incident from NHK ni Youkoso - Episode 21 (11:12 to 11:34). The main character Sato is escorting his friend Yamazaki to a subway station to bid final adieu to him. Yamazaki is a game creator (gal games) and MC helps him to create one. I have written below a short piece of dialogue (writing it from the English subtitles) between the two at the subway station:
Sato: Sorry
Yamazaki: If you visit home, be absolutely sure you get in touch
Sato: Sure..
Yamazaki: See you around.
Sato (a bit panicked): Yamazaki..
Yamazaki: Don't let the world beat you, Sato
Sato (this main character seems even more panicked and shouts in Japanese): You are not going home defeated, right?!
Yamazaki chuckles.
... ..
Now my question to all the fellow members is, why does the character shout here? It seems a bit awkwardly and reluctantly placed. This is one instance which I have cited here but I have seen this sort of thing in other animes before. I can't exactly remember the names.
