Ethereal Genesis Online: Black Jade

Jada Blackburn just graduated from high school with her girlfriend Ember. She had planned on spending the summer doing nothing but laze around and play the new VRMMORPG her dad helped develop. But no, she will be spending her next 10 years stuck in said game with her childhood sweetheart/girlfriend, reluctantly (on her part) climbing the stupid 100 floor tower in hopes of defeating the stupid Final boss. And for some reason the other players are calling her and Ember the "Yandere Couple." What does that even mean?!
