Who's the killer

Trust, a powerful word. 2221,many has changed.

Friendship is much rare than before, trust is endangered,your life is important, no one is the main protagonist, everyone is affected....

will friendship destroy everything or...
will it make the world better? How well do you know your friends? Are you sure that there is no traitor???

sa 7 magkakaibigan, may taksil ba? may traidor?
si Samantha kaya?
si Bryce??
si Khat?
si Thea??
si Dan ba?
si Raphael ba?
o si Thanya ang kakambal ni thea??

sa mundo kung saan magpapatayan ang tao para mabuhay, para makahiganti.

sino kaya? Sino ang killer? Hanggang saan nila kayang dalhin ang paghihiganti, kaya pa ba nila mabuhay ng matiwasay??
