As Zach and Aria were going to take their relationship to the next level by going intimate, Zach wanted to tell her everything before that.
All this time, he was hiding it as there was no rush to tell her because neither of them was going anywhere, but now that their relationship was advancing, Zach thought it would be for the best to come out clean.
He didn't want Aria to find out about that from another source that could possibly damage their well-going relationship.
However, never in his wildest dream had he imagined Aria to know about it.
"You… knew…?" Zach asked while stuttering.
"I have had my suspicions."
"Since how long? And what do you know?" Zach asked with a curious and anxious look on his face.
His heart was beating so fast that even Aria could hear it clearly. It was as though he was standing in front of a god and getting his judgment, although his current situation was quite similar to that.
