His gaze was all on Lila. When he's with her, his eyes would be all over her. However, Lila used to think he was watching her all the time to find mistakes in her but the truth is he couldn't take his eyes off her beautiful face. Sometimes he makes an effort to say how much he loves her, how marvelous she is, how lucky he is to have her and how he wanted to live with her forever but he couldn't.
At least, he wanted to say all of this before his death.
From the very first moment, he knew that Lila deserves someone better than him. He still remembers the disappointment on her face when he said he wants to marry her.
She always saw him with fear, she never admitted her true feelings about him and lied to him on his face whenever he asked whether she loved him. He knew she didn't love him and it always made him upset and angry.
He found a strange way to get all of her attention on him. It's by hurting her.
