How such a situation came to happen?
After Feifei entered the other room, Tiane heard Ruik murmuring something. She got close to see what it was and quickly noticed that the 'dead weight' was dreaming. If that was all, it would be okay. She could have just ignored and returned to her own room. But the contents of the murmuring stopped her from doing so.
"Haha! See how the great Ruik...
is the best demon beast!...
Who cares about Tiane? Once this grandfather...
puts in the effort, someone like her can't possibly...
compare to me...."
Krune has been comparing him and Tiane ever since they met each other, so it had long since become a deeply rooted issue in Ruik's mind. It was so much that it was enough to make him even dream about it.
Hearing that, a vein popped out from Tiane's head.
She couldn't just ignore that, so she gathered her energy and tried to give Ruik a good kick.
