As the one singing with Iris, Jin Chonglin knew from the slightly detached look in her eyes that she was imagining another man standing beside her on stage right now. He had no doubt that it was his older brother, Jin Liwei, who was in her mind while singing. All the love and passion she was expressing wasn't for him but for his brother.
The thought suddenly depressed him, transforming his passionate expression into a heartbroken one. It gave his singing an extra layer of deep emotion as he sung the next part solo.
"Smitten I had followed you around
Not expecting anything in return"
His hand subconsciously extended to Iris. It was already too late when he realized what he was doing. He was about to pretend that he was just gesturing his arm as part of his singing when Iris accepted his offered hand and held it. His heart skipped a beat.
