MORNING, SENSEI! TO WORK SO EARLY IN THE DAWN, QUITE THE COMMENDABLE ENDEAVOR FROM YOUR PART.

... and what?

... I stayed up all night. Your voice is ringing in my head. Keep it low

S-sorry. You pulled an all-nighter huh.

I was thinking maybe we could have breakfast together

Later when sensei woke up after a short nap with a clear head he profusely apologized to her.
