Han had never wanted to punch someone so bad in his life before.
As soon as his phone was in his hand, he had walked out only to find a frozen Ivy standing on her spot with a hand slapped to her mouth. Curiousity and worry had gotten the best of him so he had went to check up on her. He had peeked from behind her shoulder and was positive that the sound of heart-breaking was not only Ivy's.
He was heartbroken too now, because he had trusted the love of his life in the hands of Nathan. Disappointment and disgust filled him completely as he watched the scene unfold.
If anybody listened to just their side, Nathan was the one completely wrong here but one sided stories are never true. He needed a chance for an explanation.
