Finding things out together

In the train traveling from seol to jeongdongjin. Seo-yun's thoughts: I, Han Seo-yun a seventeen year girl. This year is gonna be the start of my high school life. I'm moving to my hometown after seven years with my parents. Due to my parents work I had to shift to seol. It's been a long time since I have been there. I wonder how is there everything now? Is there gonna be anything which i can say hasn't changed? I'm gonna stay at my grandparent's house. My parents aren't moving with me because of work. Or maybe because work is more important than me. Still I'm not really having any excitement or anything to go there. I don't know why. More important thing... should I be feeling anything? The 'jeongdongjin station' is here. The Announcer says. Oh, I was overthinking the whole travel time huh? Seo-yun said getting up and dragging her trolly with her towards the exit. Should I call grandfather? He said he will pick me though. Seo-yun thought getting out of the train. Then her phone rings. It displayed grandfather on screen.And she picked it up without a second thought. Hello grandpa. She said. Seo-yun, Have you arrived safely? Grandpa said. Yeah, I've arrived grandpa. She said. Oh, good. I'm coming to pick you. Don't roam on your own okay? Grandpa said. Alright, grandpa. Oh, is that the one with the weird hat you grandpa? She said with a frown. And then hang up and walked towards him. Grandpa you were here all this time right? She said with a plain expression. Grandpa smiled and said Yeah, how did you knew that? You are good at catching things like your father. He said with a chuckle. Well, it's so like you grandpa. She said her expression softening. Not quiet a smile. Let's not talk here. Your grandma is waiting for you since she heard you are coming back. He said carrying of my bag. You don't have to do this grandpa. She said worried. I do look old but I've more stamina than young ones you know seo-yun. He said with a proud expression. Yeah, right grandpa. She said walking towards the car. While being in the car. Seo-yun looked out of the window the whole time. And thought. This whole place has a lot. It's not surprising. Places also changes with time like people...
