Derek stays paralyzed in fear as my locket floats out from it's hiding spot in my hoody and begins to glow a rich purple as smoke of the same color exits the cracks of the locket.

The smoke was thick and bent, curved, shaped and formed what looked like the outline of a person, as the smoke dissipated, it reveeled none other than Sun-Hi's dead relative Channyeol Young.

An evil smirk played across his lips, meeting his eyes as he stared Derek down.

In a flash of quick movements, Derek was on the ground yelling in fear as Channyeol laughed maniacally before charging him again only to jump on top of his stomach, feet first, disappearing in purple smoke with Derek yelling.

Then his eyes turned purple and he stood, bowing with a fist to his chest to Sun-Hi who could only clutch her locket with her mouth wide open, eyes bulging in fear.

"I am yours to command boseu Sun-Hi Whang"

Sun-Hi was speechless.

Flashback

"I want you to have this Sun-Hi.
You'll need it back in Gotham seeing how dangerous the place is.
It holds the power of our ancestors. Only a Whang  can use it.
To others it'll just be like any other locket unless they open it"
"What happens if they open it appa?"
He looked at me gravely with a small sad smile "Then all our ancestors, good and evil, will come back for revenge."
"You mean ghosts?"
"Any ghost you summon will be at your service until you dismiss them from your service. Then it's up to them what to do."

End of flashback.

I had only laughed, thinking that he was joking but I know now that he wasn't.

Channyeol died as a teen 12 years ago when he was 16 by being beat up to death by a gang because he got in they're way when they tried to get to his father for betraying them.

"I... Channyeol?"
Derek's possessed body stood up straight and nodded slightly confirming Sun-Hi's suspicions.

"Dangsin-ui seobiseueseo"*¹
"C-can you get out of h-his..."
"Body?" Channyeol guessed seeing Sun-Hi at a loss for words.

She nodded vigorously in response.

Purple smoke left Derek's body and formed Channyeol's right beside Sun-Hi as Derek crumpled to the ground in a hump.

"I-is he...?"
"Dead? No. He only fainted. Being possessed has that side effect. I suggest we go now before he wakes up. You have school remember?" Channyeol answered.

Sun-Hi poked a finger at his chest but it was solid.

"If you're wondering why you are able to touch me without your hands going through me it's because you're the one that summoned me"

Fangirl 100% .
I have a ghost for a body guard!

***

I walked down the school corridors pretending to talk on my cellphone when in reality I was talking to Channyeol who was walking right beside me.

Only I could control who saw him.
In short I had to always have a thought of him in my head or I would lose control and whoever could see him.

"This is complicated Channyeol oppa!" I whined into the phone.

"I suppose you're just going to have to deal with it. Not my fault you got chosen to hold the locket instead of your twin."

"How do you know about my twin?"

"I died only two months after you two were born. Long enough for me to know that you two existed and assist your parents marriage"

"Oh"

Channyeol should have been in his early thirties by now if he weren't dead...

"Hey if I can summon my dead family; can I summon others?" I asked.
I was rather curious now.

Channyeol's face grew serious "Yes, but you would need something belonging to them plus have to keep them always in mind as well as me or you lose control. Be careful with who you summon and how many Sun-Hi. This isn't a game.
It's risky."

"... Ok"
