Ru's realization

Zhao Xin felt her eyes widen. She was pretty sure that her eyeballs would fall out at any moment, her eyes were so wide. Wh..What was Ru saying?

She wanted to ask him but he wasn't looking at her. He was simply staring at their picture that was mounted on the wall. It was the four of them. Just before Zhao Min had left for his military service. She and Rou Rou had been hugging each other and posing for a picture when suddenly Min Min had come behind Rou Rou and Ru had come behind her making them jump and then explode with laughter as mama had captured the picture. That was the last time they had been together without any undercurrents.
