"Your girlfriend is already at my house, why should I sleep with you? What would it look like to Qingqing?" Song Xiaoru shot Song Xiaodong a glance before she directly left the room.
Song Xiaodong knew Song Xiaoru was no longer the same as before. He felt somewhat disappointed inside. The house had gotten bigger, there were more rooms, but it seemed the closeness he had with Song Xiaoru wasn't as it had been in the past.
In their small house before, they shared a room, so there was little in the way of privacy, but now things were different. They each had their own rooms, and it was no longer possible to be as close as before.
Song Xiaodong recognized this was the proper way, this was how a normal brother and sister relationship should be, yet years of habit led to some sadness, which was, after all, quite natural.
