One day, Jaejoong had come home with a child by his side. 

None of them had questioned it; it was Jaejoong after all. It wasn’t a strange occurrence, and it was easy, at the time, for them to assume that Jaejoong was just being his normal kind and giving self. 

Maybe the kid was lost, and Jaejoong was allowing him to stay there until the child’s mother was able to pick him up.

Maybe the kid was a nephew of Jaejoong’s, and he was simply taking care of him for his sister.

Maybe this; maybe that; it really didn’t make a difference.

At that moment, it really had been just a common Jaejoong happening. 

It’s in retrospect, however, that they realize. They realize that at that moment- that moment, they could have made a difference. 
And, that maybe, maybe, if they had done something at that time, that maybe… just maybe… 

Even now, they still aren’t able to finish that sentence.
