Who is always there to help you when you need it badly?

My order sister always help me. She 28 years old. So we are three years apart. She have many experience more than me. So when I was have some troubles, I asked her for what can I do. When I was move in the Seoul at that time, I didn\'t adjust in new area. It\'s no hard to me and I need to help always. And I think her need someone too. In fact, We were help each other. Last time, when I was going home late at night after part time work. I was scared about some people who drunk. Once, someone followed me. So I called my sister to pick up me And she came to me with pleasure. In opposite situation I helped her also. When I was not work in company. It was rainy day, I was going her company to pick her up and bring her umbrella. Beside that, we shared interested things. We bought something to need each other. But now we aren\'t live together anymore. So sometimes I miss her.but we are always bother each other. My sister is the most reliable and important family for me
