IU then went on to share a story of the only time Lee Jong Hoon lost his temper and fought back.

I was giving him a hard time as usual, but he snapped and threw his robot at me. But the robot hit the clock behind me, and it fell on my head, which hurt me. It was me who was hurt, but he cried because he felt bad.

In particular, IU detailed the time when she was the meanest to her little brother.

The time I harassed him the most was when I locked him up in my grandmother’s room and pushed him out of anger.

I pushed you hard back then. Is your back all right now?

Now that you say it, I can’t move my body the way I want anymore.

In a recent interview with GQ Korea, IU expressed her wishes to reconcile with her brother and confessed that she used to be hard on him.

I used to hit my brother when he wouldn’t listen, and we ended up becoming awkward with each other when we grew up.
