Parody of that one chapter when Nobita and Doraemon go back in time when Nobita's dad was a child to find out who his first love was....
I remember that chapter, too. This kind of plot might become a little nasty under some ero-artist's standard if you know what I meant, lol
That girl...she had long, red hair and big, up-tilted eyes...Even now i still remember...The Girl Who Resembles a Tiger Lily.She gave me chocolate, then vanished into the sunset......how tasty that chocolate was.
