How to be a dark hero's daughter X OC

Ch-12(Professor Siebel Part-1)

"Nice to meet you, lady. My name is Siebel."

"Yes. I'm Selen." 'he is kinda familiar, but with who?'

I got frustrated and answered, I don't like others calling my name so I just gave an abbreviation.

Siebel looked at me and smiled.

"Why are you laughing?" I asked.

"Oh no, no. You are so cute. Like a mad puppy."

"I'm not a puppy."

I shook my head and finally looked up to Dr. Siebel.

"Are you sure you are a doctor? All the doctors I met were old men."

"Ah, I'm not that old yet. It's just that people like me are geniuses. Who earn many degrees at a young age. Duke has brought you to see if you're the same as me or the same as Lady Leticia. People like me can help the lady."

"Thank you. But I won't be needing help."  'Why can't I remember who he is similar to?"

When I said it in a firm tone, Dr. Siebel laughed again.

"You're really cute. Don't worry, lady. In noble families, this also happens all the time."

"What are you talking about?"

"All parents believe that their child is a genius and bring them to me."

"If the lady in front of me is a true genius, she will need my help."

"Okay."

"I hear you haven't studied the letter fully yet. So let us do it verbally. Do you want to have fun solving my problems? Let's see, somewhere there was a test ticket ..."

Dr. Siebel hurried to the table.

"Ouch."

Then he hit the corner of the table. He bent down and rubbed his shin.

"Are you okay?"

"Oh yeah. I'm always such a muddler. At least it doesn't bleed."

Siebel laughed softly. I just realized that Siebel was quite handsome.

'He's a bit clumsy.'

I stared at him and thought.

"Let's start right now. Haha..."

And Dr. Siebel laid out his puzzles.

"How long can you solve this labyrinth?"

He showed me a complex maze, showed numbers, told me chains of cause and effect, asked about my associations, and so on ad infinitum.

Most were answerable, and some I really couldn't solve.

"Hmm, so... Is the reason the princess couldn't get out of the maze because the first knight blocked the road? And this road is blocked in this way..."

However, getting used to it, Siebel's riddles seemed pretty funny. 

Several hours passed in this way. After she finished talking, Siebel spoke to me.

"I need to summarize the test results. If you wait here for a while, the Duke will arrive soon."

"Yes," I nodded. The thought about what happened with the Duke and started to get a little angry.

'Leticia should tell him to buy me something to please my anger. If he doesn't say sorry then I am not going to talk to him till the day of the play.'

I remembered the words of Dr. Siebel.
