*Yerin POV

"Yerin-unnie, Help me"

I heard her voice again, but every direction i run, i can't find anything, only darkness. i can't see anything

"Eunbi-ah, where are you? please tell me" i cried, kneeling down, too tired to keep moving

i keep getting the same dream for the last 2 years. it's telling me something but i don't know what, Eunbi's body are in my house, staying unconscious for the last two years. it's alive, but i don't know if she will ever wake up. all i can do is to keep on checking her pulse over and over again to make sure she haven't died yet.

*beep beep

my phone rings, i check to see that it's a message from joy 

"Yerin-ah, Are you home? i have to meet you now, there are something important i have to tell you" Joy says, i can sense urgency in her voice

"yeah, i am home, what is it joy-ah?" i ask

"It's about eunbi, i'll tell you when i'm there" Joy says disconnecting our call

*End of Yerin POV

15 minutes after the call, Red Velvet agents all arrive at Yerin's house together with the newlywed wonha and yumji couple.

"what is it that you ask all of us to gather here?" Sowon begin asking

"well, i know that you guys want to save Eunbi right?" Irene says, looking at all of them

"of course, what kind of question is that?" Umji answer with annoyance clear on her face

"Then, it's the same as us, all 10 of us have one final mission to save the one dear to us" Irene says

"let me explain" Irene continues

*flashback

Irene and seulgi are in their house thinking of what joy have told them about Yerin's constant dream and Eunbi's condition. suddenly, an idea come to Irene's mind.

"Seulgi-ah, do you remember what happen during the final battle between Eunbi and heulin?" Irene ask seulgi

"no, why?" Seulgi answer shortly, as she is immersed in playing battleground with joy

Irene smack Seulgi in her head

"Can you please be serious for one minute? this is very important to save our friend's live" Irene says, annoyed by her little sister's nonchalant answer

"okay, what i remember is, when the two final attack collide, time and space continuum is shaking, distabilizing our power for a few seconds" Seulgi says, remembering what happen back then

"do you think it is possible that seulgi's conciousness is being transferred to other dimension, and she is trapped there?" Irene says

"well, there is always that possibility. it's either she is trapped in time of constant battle with heulin, or her conciousness is transferred to other dimension altogether" Seulgi answered, giving her full concentration on the conversation since she is killed anyway

"Wanna do a dimensional journey through time and space to check?" irene says

"Well, if that is what we gotta do, let's go" Seulgi says

both sister go through several dimension before they found what they are looking for. Eunbi is trapped in a pocket dimension where she is chained down by a dark chain that try to kill her, she is surviving solely because of her light power constantly negating the dark chain's power. they try to break the chain to no avail, their power is not enough, they need someone that are extremely strong

"YERIN" they both yell

*end of flashback

"so, in other word, we need yerin and the rest you you guys power to try and breaking that chain" Irene explains

"Then, what are we waiting for? Let's go save her" Yerin says, suddenly standing up.

The rest of them silently stand up, preparing to save their friends

Irene and seulgi use all their power to open a portal to that dimension

as soon as they arrive, they see the chain that tied up Eunbi's body. Yerin rush forward, trying to call out to eunbi, but to no avail. She has lost conciousness for 2 whole years. Yerin try to pull on the chain, but even the strongest(in term of pure physical power) human alive can't break the chain. the rest of them use all their power to pull the chain. suddenly, the chain disappear and take other form, the form that they know very well. Hwang SinB.

"SinB?" Yerin says

"It's been a while you guys. i was worried that you guys will never shows up, i'm sorry i have to do this. when heulin's and eunbi's power collide, their power and eunbi's conciousness were thrown to this empty dimension, part of their power fused to revive me. the problem is, i can't leave this place and if eunbi's power leave her, her conciousness will fade, that is why i tie them together using my power until someone come" SinB says

"please, bring her back to your world and make sure that she survive" SinB continues

the rest of them just nod and walk to the portal with eunbi before Umji says "Nice to see you again SinB-ah, thanks for everything"

SinB just nod and see them off

*Real world

Eunbi recover 2 weeks after they return to their world, as soon as she recover, Yerin update her on whatever happen in her absence, both wonha and yumji couple tell her to propose to Yerin because they want to have their honeymoon together and they have postpone it long enough. sure enough, 3 months after she recover, Yerin and SinB got married, without any delay, as soon as they are done with the marriage celebration, all 6 gfriend member go on their joint honeymoon to europe. when they return, they are recruited by Source agency to become an agent, they are put in a team, called the Guardian Angel

finally it's really done. i am actually tempted to make a sequel to this, but since i still have my work in progress and my work is extremely hectic, i don't know if i have the time to write another story. that is why i decide to end it here. sorry if the ending is rushed and not good enough. This is the best i could think of right now because my brain is having a mental breakdown right now
