Because he knows Big Sister's weak spot, Su Qing subconsciously feels that no matter what they do, their father-and-mother-like Big Sister Su won't hold it against them.
It's like how no parent can reject the flesh that came from their own body.
Although they didn't come from Big Sister Su's body, they're pretty much the same.
Elder sister as mother, elder brother as father... it's not just a saying.
In the past life, everyone thought he built his fortune from scratch; in reality, even Su Mo and Su Bing didn't know it wasn't entirely true.
The initial startup capital for his business was provided by Big Sister.
He doesn't know how she managed to get such a large sum of money, nor does he care. He only cares about the result.
Maybe she sold everything she had, or perhaps it was some other method....
But after he succeeded, he repaid it a hundredfold and this issue was settled, nothing more to say.
Last life, she could be so selfless towards them siblings, why not this life?
