Kris may feel that he was reluctant to leave Yu Holea but in reality, he was traumatized.
He was so much traumatized that he subconsciously rejected the word family.
The reason why he let Yu Holea near because, in his subconscious mind other than Yu Holea, everyone wanted to hurt him.
However, he was able to mask it in a very good manner.
If Yu Holea wasn't wrong then this trauma would be triggered whenever he will look at any musical instruments.
Qiao Heng understood Yu Holea's answer and asked in a soft voice,
"Can...Can you let me meet him...just once..."
Yu Holea shook her head with difficulty.
It would have been fine if Kris had only been traumatized, it could have been healed after several rounds of treatment but after his disfigurement, Kris started developing inferior complexity and became more introverted.
