"Remember? Your promise to me?"
"I will always trust you unconditionally."
"But you should have forgotten about that now, because..."
"It was me who broke our promise to you first."
"So,"
"That's what I owe you. Please don't feel guilty for me anymore, and you don't need to promise me anything."
"It's not that I gave up on you, but that I gave up on myself."
"Please forget about me. We are no longer the innocent and carefree selves we used to be."
"I will leave and never appear in front of you again."
"So, bye."
"Never again."
PS: This is a story that happened when the Internet King was in high school, so it has nothing to do with the plot.
