（今日も仕事疲れたなー。学生の頃はあんなに楽だったのに……）
☆「そうだな、若い頃というのは多少の青臭いところもあるが、
それはそれでよりよいものだ。
私も昔は科学者の端くれとして大層な理念に
燃えていたものだ」
「だ、誰だすか！？貴方は？」
☆「しかし、ノスタルジーというものは浸りすぎると
毒にもなる。以後気をつけたまえ」
「は、はぁ……えっと」
☆「君と再び出会わないことを祈っている」
「変な人……何だったんだろう？」

(Now today too, I'm tired out from work again. I miss those easy days, like back when I was a student.....)
☆ "Well, it's true that youth brings with it some amount of immaturity,
but that's what makes it good.
I, too, was once an unimportant scientist, and would get worked up
over my lofty ideals."
"Who, who are you!??"
☆ "--however, drown yourself too much in nostalgia and you could wind up suffering for it.
Please be careful going forward..."
"Aaah....... well"
☆ "...I pray that I won't ever see you again."
"What a strange man...... what could that have been for?"
