Do I tell

Ji-Sung is waiting at the bus stop. He is going to the park.
He meets some boys from school, Scott and his friend, Mike.
“Hi, Ji-Sung,” says Scott.
Ji-Sung says, “Oh, hi! What are you doing here?” he asks.
“Nothing much,” says Mike. “Ji-Sung, where are you going?”

　　Nothing much：何も（・・・ない）

“I’m going to the park,” says Ji-Sung.
“Good. We’re going there, too,” says Scott.
“Oh,” says Ji-Sung. He asks, “What’s that in your bag, Scott?”
Scott says, “Oh, this? It’s paint.”
“Paint? What are you going to paint?” asks Ji-Sung. “Anything,” says Scott.
