V-려고 했는데
Use this pattern after a verb stem to mean that someone tried or intended to do something, but the situation changed or an unexpected result followed. It is very useful for short, everyday stories with contrast. Example: "자리에 앉으려고 했는데 사람이 많았어요." This means "I tried to sit down, but there were many people." You can reuse it whenever one action is interrupted or followed by a different result.
자리에 앉으려고 했는데 사람이 많았어요.
I tried to sit down, but there were many people.
