ECLAIRE ran away.
After making an embarrassing slip of the tongue in front of Graham earlier, she ran away because she couldn't handle the heat.
She could still remember how their conversation had gone through…
["I'm sorry, noona. I know that I should have consulted you first. I talked to some of our schoolmates, and I told them that our relationship is going strong."]
["Well, did you lie?"]
["Huh?"]
["What?"]
She must have gone crazy to utter such an embarrassing thing!
[I practically admitted that I like being in a relationship with Graham even if it's just a fake relationship!]
And worse?
[I said that right in front of Graham's face!]
"I can tell you're having an internal debate with yourself," Nathaniel commented while looking at her. "Now I'm curious as to why you look so flustered, Eclaire."
Oh, right.
