He could ignore a man like Ren Weimin but not Lan Meifeng.
She is just like him. She idolizes his sister just like he does.
Under all the farce that happened ten years ago, it could be said that it was Lan Meifeng that suffered the most. She did not do anything and yet she had to be separated from her idol.
It was Ren Weimin that dumped Shao Rong.
It was Shao Rong that decided to not go back to them.
In the end, what did Lan Meifeng do? Nothing. All she could do was accept her fate and look on.
Shao Kong doesn't know how he would live if he were to be separated from his sister whom he idolizes like a Goddess.
Hence the reason he couldn't ignore Lan Meifeng but instead he looks up to her and thus behaved so well in front of her.
Ren Weimin sighed and said, "I couldn't do anything at that time. You don't know what happened on my end."
