Well....... I need help!

Whoever can take the time and help me, I'll appreciate it a lot!

I have an idea for a Hwarang au fic, but I have no idea if I should use the Hwarang cast with their real names or their character names. 

If you think the plot will help you think better, you can tell me and I'll edit this to include the plot and the info I have so far. 

Who knew that Minho would appeal to me more with the long hair? And I can honestly and officially say that I have Second Lead Syndrome, yes, don't think I can handle Sam Mek Jong (?) that easily!!!

But no one outshines my baby Tae!!!!!!!!
