Just as Niylah was able to hear the shenanigans of Ariel and Damien, Kenneth was also able to catch a few sentences and words here and there.
For example, he heard Ariel saying, 'Damien, you can't just teleport inside my room!' and Damien saying, 'This is going to be your real first kiss.'
That alone was enough for him to know what Damien tried to do with Ariel. Right after he had figured out Damien's intention, he had sprinted out of his room so that he could drag Damien's arse out of Ariel's room.
However, when he went outside, his ears caught Ariel's moans. Though Ariel was trying to resist the temptation at that time when he heard it, Kenneth also easily misunderstood those moans.
He felt heartbroken. Ariel was his first kiss. She had also said that he was her first. But right now, she was most probably becoming the first kiss for Damien as well.
