Originally, Cheng Guodong found this old man quite displeasing, eccentric, and too close to Little Taotie, like an old guy with some ulterior motives.
But now that he knew his true identity, he could understand everything he had done, realizing that his intention was just innocently wanting to get close to Little Taotie, wanting to hear Little Taotie call him 'grandpa'; Cheng Guodong couldn't help but feel some pity for him.
In fact, this matter was an unwarranted disaster for the Tao Family as well, their perfectly fine child was swapped, and they never mistreated the nanny. It was purely the nanny's personal greed.
The old man had been blaming himself for being careless at the time, not staying by his pregnant daughter-in-law's side, going out with his wife to pray for a granddaughter, which gave the nanny the opportunity.
