What's with you all of a sudden...?

What happened exactly?

That was the only time Sensei seriously pissed me off...

To give an analogy......

I was asked to develop a vehicle that can cross the ocean.

Then one day, after frantically building a raft, I was suddenly handed the blueprints to an airplane... Something like that.

Haa...? There's no point in giving airplane blueprints to someone who can only build rafts...

......Yeah, well, the real victim wasn't me,

but the guy that made the blueprints......
