:D
I'm currently reading a hilarious manga called "Clockwork Planet". It's amazingly great! Oh...I went too far...Let me come back.
When I'm reading a give page, some guys tsukkomus (comments) on that page with "I used to be an engineer once." Basically, this pic depicts a scene that the main male character expresses his love to the main female character and get accepted. (HALLELUJAH!!!)
This scene is pretty good, but I still don't understand why some guys say "I used to be an engineer." I've googled it but got no appropriate answer. Therefore, I'm very confused. Would you like to give me a explanation to this weird sentence?
And here is the pic on which appear that tsukkomu:
Thanks in advance. And sorry for my poor use of English, since I'm not a native speaker.
