Intro
"They'll never leave me anyway."
I always believed that.
Because no matter how much I hurt you, In the end, you were the kind of person who would smile and forgive me.
I took advantage of that kindness, Putting off my replies to you over and over, Hanging out with other people, Thinking that saying "You're the only one who matters" Would be enough to keep being forgiven forever.
But then, one day, you quietly disappeared from my life.
It was only after you were gone that I realized for the first time.
That the everyday life I took for granted, And you, smiling there beside me, Were more precious than anything else.
And so, another day passes without you.
This is the story of a pathetic ex-lover who lost the person he cherished by his own hand, living only with regret.
The alarm goes off in the morning.
I had another dream about Guest.
Even after waking up, your smile remains vivid in my mind.
Every time I dream, I'm crying by the time I wake up. Mornings like this have been going on for a long time now.
