Her brother told her that someone would always look after her when he died. He promised her that the person who is watching her would always be there for her when she needs someone to talk too. The day her brother died she got a text.

From: L

As I promised your brother I would be watching over you, so don't cry Joo Jung.

When you are happy, text me.

When you are sad, text me.

When you're feeling gloomy, text me.

You can tell me the most randomness moment of the day.

I'll be here for you.

So don't cry.

You don't want your brother to see you sad right.

To: Lee Joo Jung

That day on Joo Jung would text L everyday without knowing who he is, but now a high schooler she's getting curious.
