Something Bugs Me

What is this uncomfortable feeling?

Henrie was the one who turned around from that noble lady, but why did he hate it? He rested the back of his head on the chair and thought about the incident. 

Something bugged her. Thea was crying, wasn't she? That noble lady wiped the tears from Thea's eyes, didn't she? Was there any other lady willing to go that far for a maid? 

Henrie's chest tightened. He tried to distract his mind from dwelling on that scene through work. But instead of being successful, Henrie ended up messing up his work. 

Mr. Hermann put a stop to Henrie's efforts. "Your Highness, why don't you get fresh air? I'm afraid things will only get worse with your fast-paced mistakes."

To prevent Henrie from declining the idea, Mr. Hermann spread the papers on the table, pointing at the spots where Henrie scribbled things where he wasn't supposed to.
