He decides to process it, then faces a lecture from Ingrid.

Sylvain considered using the Note again, but as Byleth stood up, now back to her senses, but not questioning her actions, he decided against it for now.

He groaned as he did have to hear a few words about his behavior from Byleth, as if she hadn't just given him head out of the blue, but he soon enough got out of it, and headed back to his quarters. He decided on getting the assignment out of the way before considering using the Sex Note further, and got to writing about the practical advantages of lances, such as how even an elite group of calvary could be brought down by a moderately trained formation with a line of said weapons extended.

Then he heard a banging on his door, and groaned, "What now?"

"Sylvan, open up!" Ingrid's voice shouted. "You got yourself into trouble with our Professor on the first week, so you're not getting out of a tongue lashing from me!"

Sylvain sighed. Of course it was his own personal mother hen coming to peck him... He then glanced at the Note, and his mind raced.
