V-고 싶다
Add -고 싶다 to a verb stem to say that you want to do something. It is very common for personal wishes and intentions. In the story, this appears in '말을 걸고 싶었지만', which means the narrator wanted to start a conversation but did not. Example: '저는 바닷가를 걷고 싶어요.' = 'I want to walk along the beach.'
저는 바닷가를 걷고 싶어요.
I want to walk along the beach.
