Forever Twintails
"However, after you get past that is when you find true love."
"True Love..."
"You should have learned your lesson now. Even-"
"Of course! That's it!"
"I wasn't finished, I meant to say-"
"No, I get it now! To reach the apex of love for twintails, I can't just be a girl with twintails or a twintail-obsessed man! I have to be more, to ascend to greater heights!"
"No, that's not what I wanted to say-"
"I understand now! I have no more doubts!"
"Listen to me, Nimconpoop!"
"Let's fight together! No, let's become one! To become the greatest twintails a girl has ever worn!"
"I'm not going to- Wait, what are you doing? No, stop, I didn't mean to-"
And so.
Several days later.
