"Nayoung ah!" Ong came to see Nayoung who sitting alone in the garden

"Yah Ong! You shocked me" she held her chest with both hands

"Nayoung, can you come with me to the premiere of a new movie this afternoon? I have two tickets but I don't know who to go with" asked Ong

"Movie? This afternoon?"

"Yes, this will be wasted if the ticket is not used"

Nayoung thought, she had to pick up Sejeong today as her duty but on the other side she really want to watch a movie. She was thinking hard and decided to go with Ong, she was sure that Sejeong can go home alone.

"I think I can, but let me tell my sister first"

"Ok" Ong smiled, he was one step closer to getting to know Nayoung. He knew that his heart starting to like Nayoung.

Nayoung wanted to call Sejeong but she sent a message instead, she didn't want to disturb her.

*Sejeongah, sorry today I can't pick you from school. I've another thing to do. Can you go home alone?*

*Cling* a message arrived at Sejeong's phone, she read it

"Ehmm... I think she has something important to do" she said to herself and replied it

*It's ok unnie, I can go home alone*

*Go home with a taxi. Don't take a vehicle other than taxi, understand?*

*Yep, I understand. I'm not a child anymore so stop worrying about me *

*You are still a baby in my eyes, but I believe in you this time. Be careful my big baby*

Sejeong smiled after reading it, then she replied with many heart emoticon. Nayoung and Ong went to the cinema after finishing their lunch

It was a rainy afternoon, Sejeong was waiting for a taxi at the bus stop near her school. But because of the rain it was a bit difficult to get a taxi. It was getting late and she was still at the bus stop. Finally she took an idea of ​​taking a bus instead.
