Inspiration:

So I was swinging alone in a park one day and the idea just came to me

So the main character lost a neighbor crush when she/he was a kid and ever since then, she/he just couldn't talk to people anymore. She/he become afraid to talk to people, too afraid to become attached to them. She/he never feels safe, even though she/he is alone. She/he soon finds a place where she can just relax for a while. To just, not think. To feel the sense of happiness again even just for a while. It's the swing at the park no one actually ever goes inside. After she/he found out how much happiness it brings to him/her, she/he will find time to go to that park every day. One day, right before she/he sits on the swing "I wish (the neighbor crush name) is with me everytime I miss him/her" She said. "But I am here with you" She/he heard a voice right next to her/her
