(FLASHBACK)

"time for plan B" L said seriously looking at the han river 

"i know weeks from now and it will be full moon i know they'll grab that chance" woohyun added 

"but who will take care of chaerin?" seungyeol asked 

"I know one person we could count on" L looked at them smiling and one by one they got what he meant

"let's tell her immediately" hoya stated 

then the boys went to her house and talked to her

---------------------------------------------------------------

"Noona! we need you're help" L said to her "of course you can! what can i do for you?" she asked them

"Pls take care of Chaerin for us pls!" he added although his face seem blank his eyes showed pleading one

"oh is this the unique cute girl who were always with you guys? she asked making them all nodd

"Okay! it seems she's good and different from those es" she said, her foreheads creased as she said es

"so here's the plan....." L said

1. We will give an order to the student to bully her and then when its the right time approach her and secretly put the tracker on her neck
2. always be with her and protect her from student (we know students won't harm you) and those other devils that could smell her. 
3. as much as possible let her stay at your house so that beast won't invite her or come near her
4. tell her how much you despise us

Tiffany nodded in approval and smiled at them "this will be exciting" she suddenly said earning smirks and grin from them. Eventhough its can't be noticed , she was considered as one of the greatest fighter in their world. 

"Thank you noona!" they all bowed down to her in respect

"Why are you making her despise you anyway?" she asked them 

"because she thought beast are human like her and they befriend her, as an innocent girl like her she was caught in their bait and we want her to realize that they're not good enough as she thinks" L explained to her

"don't you think that's too harsh?" tiffany questioned again

"well we know that but i think she can learn from the hard way" L said thinking that she will be hurt in the end 

"oh but wait why are you leaving suddenly?" she questioned them making them serious again

"Father told me that there is a problem in the underworld and they needed us to fix the chaos, and its also time for us to train for chaerin and those bastard beast!" L enunciate to her making the boys nodd

"oh i heard of that also.. i heard followers of uncle and beast were revolting against you and your father" she stated seeing a worried expression on her face

"don't worry noona we will be back.. and when that time comes surely we're stronger than before" L assured her 

It's time for them to leave as the she hugged her one by one giving her sisterly love to them 

"I'll also assure you to take good care of her" she once again said as she waved goodbye to them and thought of how she's going to start the plan

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

"are you sure she's gonna be okay?" Hoya patted L's shoulders and asked him

"yes i know she will...." he simply replied lost in his thoughts

*after all she's not just an ordinary human*

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------

for those who were kinda confused let me clarify that L is also myungsoo :D
