Sorry For Embarrassing You

The relationship between Gu Juexi and Gu Tianmu was a profound one. 

Gu Juexi had been trying to get his father's attention since he was young and had put a lot of effort into it, so when he kept getting disappointed, he started to hate Gu Tianmu. 

Many years later, Gu Juexi found out that Gu Tianmu only hated him because he was misled. The feeling when he found out the truth was ineffable, but it was also very frustrating. 

As for Gu Tianmu, he was a man who was excited to find out he was going to be a father at first and was later deceived into distancing his son who he loved so much. 

Many years later, he felt regret when he found out that he was misled since the beginning and it made him lose his son almost completely. 

So in reality, Gu Tianmu never intended to leave, and Gu Juexi never looked like he was trying to get rid of his father for real.
