"I need to make more money," Fang murmured to himself. He had been thinking that he had tons and tons of money – but now that Rudy pointed out the details to him, he realised that he didn't have all that much left. Of course, it was still enough for him to live a comfortable life to an old age, but Fang didn't want that any more. Now that he had seen how happy Ren became with a little pampering from Fang's side, Fang was determined to pamper Ren every single day until they were both old, white haired men who would leave the world on the same day at the same time – they would always be together, be it in life or in death!
And to pamper Ren to his heart's content, Fang needed to earn lots and lots and lots of money!
Fang suddenly understood how Ren must have been feeling earlier when Ren had been in a hurry to earn money for buying that private island for them.
