WHEN WILL YOU START THE PLAN?

WHEN Luo Yan and Luo Ren returned home, it was almost three o'clock in the afternoon.  Walking inside the house, they saw their younger brother at the living room looking a bit frantic while typing something on his phone.  No, it's probably dialing a number because after he did that, he put the phone on his ear.

Just as Luo Jin did that, the phone in Luo Yan's pocket rang.  Both were startled by this and both ended up looking at each other.

Luo Jin immediately put down his phone and walked up to them.  "Yan, Auntie Cheng said that you suddenly left after lunch, what happened?"
