"Even the Time Machine no longer had any restrictions?"
"Didn't you say before that although the Time Machine could travel back to the past, it would cause unpredictable consequences?"

"Though in that case, it would be equivalent to changing nothing at all."
Doraemon said as he stuffed dorayaki into his mouth and nodded.
"That's still acceptable, then."
