Cao Qiuhua fell asleep quickly, having drunk far too much and had not at all considered that there were still two other people here; she virtually occupied half of the bed, leaving only a tiny half for Song Xiaoru and Song Xiaodong.
For two adults to lie in such a cramped space was obviously quite a squeeze.
To avoid falling off, Song Xiaodong had no choice but to cling to Song Xiaoru, wrapping his arms around her little belly. Holding Song Xiaoru like this, Song Xiaodong didn't have any other thoughts. In his heart, he naturally treated Song Xiaoru as his own sister.
He adored her, loved her, and would often tease and play tricks on her, but he had never had any improper thoughts about Song Xiaoru. Holding her now, he just felt especially warm inside and very content.
