"What are these,ahjussi?"Leo's pure voice asks.

"Um?"The 'ahjussi' turns and looks at Leo.

"These."Leo points to the music sheets on the dining table.

"These are music sheets,little guy."Sunggyu smiles and pats Leo's head.

"I'm not a little guy,I'm a cutie pie."Leo says then does a cute face.

"Okay okay cutie pie."Sunggyu smiles and gently ruffles Leo's hair.

"What are music sheets?"Leo asks again.

"Music sheets are papers that you have lots of music notes of it,and according to the music notes on it,you can play a song with a piano or a violin,you can even play it with many other music instruments."Sunggyu smiles and says.

"Whoa ahjussi you are so clever!"Leo claps and says.

"I'm interested,but I don't know how to look at these music notes."Leo pouts slightly.

"We can learn it slowly cutie pie.So what's your name?"Sunggyu asks.

"Leo."Leo answers.

"Leo?Let me see..."Sunggyu searches through the music sheets,and then takes out one of them.

"Here."Sunggyu hands the music sheet to Leo.

"What is this?"Leo asks.

"It's the track named 'Hakuna Matata' from the cartoon 'Lion King'.Did you watch 'Lion King'?"Sunggyu asks.

"Yes!Simba is so cool!"Leo cheers.

"It means 'no worries'."Sunggyu smiles.

"So will I start learning the notes from this track?"Leo asks.

"Yes you will."Sunggyu smiles widely.

"Ah where is Leo?!"Eunji asks anxiously when she found that she was too busy and she forgot Leo.

"I saw him with one of the tenants,learning piano."Hoya yawns and says.

"Learning piano?"Eunji is surprised.

"Yup.It seems that he is very interested."Hoya smiles.
