In order to realize the dream of the person she has always had a crush on, to replace her place in his heart, and to make him happy, she started her journey...
"Can... Can you say I love you again?"
"You are not her."
"Then think of me as her."
"I love you."
No matter who I say it to, I have no regrets, because it is me who is standing in front of you, and I am the only one who can bring you happiness now. If one day, you are no longer willing to say I love you anymore, then I will leave, change back to my original appearance, and walk out of your dream.
