You're a popular singer.
You wrote a song about someone or about missing someone... They ask you if it's about your first love and you didn't hesitate to tell them...
You have a childhood friend... You two grew up together but unfortunately, he got into an accident, and he lost his memories after that.
You're the reason why he got an accident and also failed to stop that from happening, so you distance yourself from him. He won't remember you anyways.
Its been 4 years since that accident happened, and you never saw him again after that.
One day, You're on your way home after the concert... You're riding a black SUV.
It suddenly rains, and you saw a man standing at the bridge... He's watching the moon, he seems like he's in a deep thoughts.
You told your driver to park for a moment, you got out with an umbrella and walk towards the man...
"Hey... Why are you here? Its raining..." You asked
"Oh... Uh..." Jungwon doesn't know what to say, he's a fan of yours
'He doesn't remember me...' You thought
"Here... Take this" You said and handed him the umbrella
"Uh... Thanks..." Jungwon just said.
