Gan Dewei involvement

Xian looked into Mishi's eyes who told him such a big thing which he was never able to see that his mother who was with him when Shui Zhang left them. His mother never once let him feel lonely and for the upbringing of her child, she moved ahead in life. Initial 2-3 years were tough for Xian but when Mark came into his life as his brother he was not lonely anymore. 

Biyu met every end to give her sons every single thing they wanted. Today when Xian met Shui, he acted upon the word of his father that his existence did not worth it. How could he even think about that when his existence is the most important thing for his loved ones? 

Mishi was giving light pats on his back when he came out of his thoughts. Saying 'Thank You' he pulled away when he saw the tears pouring down Mishi's cheeks. He wiped them off using his thumbs and said, "Forgive me for making you cry."
