Who's behind this?

Sometimes, the twin's smartness scares him. They are so small, but could already detect who the villain is. 

They already knew he's the one in the wrong. 

"How was school?" he asked, trying to pretend like he doesn't understand the meaning behind their gaze. 

But he seriously has forgotten the kind of kids he fathered. They will never let him off the hook. "What did you do to mommy?" Ciara asked. 

Ethan gulped and couldn't look them in the eyes. His hand clenched in a fist, as he's still in a kneeling position in front of them. 

It was like a judgement day for him. "Did you hurt her?" Clara asked, making him look up at them immediately. 

He shook his head, with his expression showing that of fear and worry, "I will never hurt her princess." he said, not wanting them to give him attitude like Diana is doing.
