"I'm Miss Hana, Kang Hana" 

Both Yuqi and Hana shake hands, making Hana the last teacher that she knows today.

"How old are you?" asked Yuqi politely. 

"25, you?" 

"I"m 23" 

"23? Wah.. I almost thought you're 19 or something. You looks like a child" 

She chuckled "Really? Oh I don't know if it's a good thing as a teacher"

"Sure not, they might treat you as a friend" she laughed. "By the way, which class you're heading this morning?" 

"Ah.. 4D"

"4D?" she looks anxious. 

"Why?" 

"Well.. nothing. Let me bring you there since I'm heading to my class as well" Hana picked collected her books on her desk before they headed to theor class while having some conversation. 

"Where do you live Miss Yuqi?" 

"I live at my parents home in Seoul but I'll move to my own apartment this week. How about you Miss Hana?"

"It's okay you can call me unnie instead. I live only a few blocks from here"

"Ohh, that's close. So, what about the 4D?"

"Hmm, most people here included some teacher don't really like the 4D"

"Are they rebellious?"

"You can say that but they don't get into fight often, but one person does. Taehyung. He got into fight often than the other. No one know how he is living out there, he got bruises all over his face" 

Yuqi's eyes widen as she is shocked to heard that. 

"The class monitor is Jungkook. But he is not that useful, he is same as the others. Basically Jungkook did nothing at all. They was a rumor, people said he murdered his brother" 

She stopped walking, so do Hana when she realize Yuqi is not by her side. 

"Yah, but don't worry. It's only a rumor, no one knows the truth but it is enough to makes everyone in this school fear of him and most gangster students in this school respected him, could be more than they respect their teacher. That's why I kinda believe the rumor" 

Yuqi sighed, she haven't take her step in her class but she is already seeing at her failure career as a teacher. 

"Suga is a sleepyhead. He sleeps all the time in the class. Whenever we sees him not asleep, we consider it as a miracle. Some said he works in a bar and we know as a minor we can't let it be but 4D never listen to us. They also hide their activity well from us"

They stopped in front of a door class. It's so quiet from outside. "So we are here. I hope you're going to be fine with the 4D and I wish you al the best. Presenting you.." she open the door for Yuqi as she is looking at her "welcome to 4D" 

Yuqi had a very clueless face, she looks into the class and to Hana back. 

"What's wrong?" asked Hana, not aware of the current
