Taemin had brought home his report card from school to show Key Umma and Jonghyun Appa, and had all A's except for an F in Korean History.

Key: "Taeminnie! You're so intelligent! What happened?"

Taemin: "embarassed from failing his umma Key Umma, I had all A's in American History, but Mr. Lee got angry at me because I was talking to his daughter and gave me an F."

Key: "Mr. Lee...DID WHAT!?"

Taemin: "I'm sorry umma. I'll try harder next time."

Key: "No. This isn't your fault! Your teacher is just a... I'm not going to swear in front of my child. Grabs his coat We are going to go have a chat with this Mr. Lee character!"

Taemin: "No. Please not tonight. I know what you could do to him and we don't need that."

Key bites his lip. His baby knows his harshness.

Key: "Okay. Tomorrow, you need to go to Mr. Lee and demand an A. You don't need to take this hate from your elders. Mr. Lee doesn't know anything and his daughter would probably love you, sweetheart."

Taemin: "Key-Umma...Really? Don't they teach you that you are supposed to respect your elders?"

Key: "Taemin...I'm your elder."

Taemin: "I understand."

Taemin sighs, leaves the room and finds Jonghyun in the hallway.

Taemin: "Jonghyun Appa? My Korean History teacher gave me an F because I talked to his daughter. What should I do?"

Jonghyun: "What?! You need to run into school tomorrow, kiss his daughter right in front of him, write your number on her hand, and smile at him! Next you need to...Taemin...?"

Taemin ran out of the room and slowly creeped towards Onew's room to find him with a foot in the vent.

Taemin: "..."

Onew: "Hello nephew!"

He gets his foot out of the vent and sits Taemin on the bed next to his chicken.

Taemin: "Uncle Onew. Could you tell me what to do if a teacher gave me an F for talking to his daughter?"

Onew: "Okay, so you stuff chicken in his mouth... puts chicken in Taemin's mouth ...Then you moon him... turns around and Taemin screams"

Taemin runs out of the room, hyperventilating at the sight he just had to see, and into Minho's room.

Taemin: "Minho hyung. Can you help me with a small problem?"

The Next Day

Taemin tries Minho's advice on Mr. Lee.

Mr. Lee: "Ugh. Hello Taemin."

Taemin: "Mr. Lee. I apologize for my behavior and I promise never to bother your daughter or yourself again. I just ask you, please could you rethink my grade for Korean History?"

Mr. Lee: "Okay. As long as you stay away from Hwa Young, You can have your A."

Taemin: "Thank you so much, Mr. Lee! It won't happen again!"
