One possible theme could be redemption. If it's about a character getting another chance, like the 'ek baar phir' (once again) part implies, they might be seeking to right past wrongs.
I'm sorry, but I'm not familiar with a specific story named 'ipkknd ek baar phir'. It could be something very niche or from a particular cultural or regional context that I'm not aware of.
The original text of Ye Xiu playing the piano in " Full Time Expert " appeared in chapter 623 of the novel. The original text read:
He walked into the living room and sat down in front of the piano. His slender fingers were placed on the keys, and for a moment, beautiful music flowed from his fingers.
This piece was a classical piano piece called Moonlight, a work of the German composer, van der Bevehn. Ye Xiu's playing skills were superb. He performed the song to its fullest, making people intoxicated after listening to it.
I don't know if this is the answer you want.

Gunga Din is fictional. It's inspired by various elements but doesn't draw from real-life events or people. The story was crafted for entertainment purposes.
The name " Yellow Spicy Dice " came from its characteristics and traditional cooking methods. Yellow Spicy Din was a common freshwater fish with three bones on its body. Among them, the word " Ding " was first seen in oracle bone inscriptions, meaning nail and also having a small head. And "spicy" referred to the burning pain when the fisherman was stabbed by the yellow spicy Ding. Therefore, the name " Yellow Spicy Dings " came from these two characteristics.
