Song Xiaodong was a bit dumbfounded. Miao Qingqing's assertiveness, combined with a bit of shamelessness, was something he had not anticipated. Such contact with the feet, if it was a gentle rubbing, could still be considered a sort of pleasure, but this kind of harsh stomping was simply torture.
But soon enough, Song Xiaodong figured it out. This was clearly Miao Qingqing's revenge; she just wanted to vent her dissatisfaction.
Understanding this, Song Xiaodong simply extended his foot a little more, allowing it to be more conveniently stepped on, letting her stomp to her heart's content.
Miao Qingqing felt Song Xiaodong's cooperation, stomping hard for a while until the anger in her heart had somewhat dissipated. She then took her foot back on her own initiative. She was not the kind of person to be unrelenting even when she was right. Seeing Song Xiaodong's attitude of acknowledging his wrongs was something she could accept.
