After Yang Xi returned to Juilliard School of Music, she turned on her phone, and Su Ruqin gave Yang Xi a call. Yet in the call, she didn't mention again that Yang Xi must break up with Ren He. Instead, from that point on, she never brought up Ren He again, merely asking indifferently how Yang Xi had been recently, and when she would be coming home for the New Year.
It was as if Ren He had vanished from the world entirely...
This was Su Ruqin's stance: since you are so determined to be with him, I will not interfere, but don't expect me to acknowledge it, at least not until you can truly walk down the aisle.
But could Su Ruqin really ignore the existence of Ren He? She could not.
