One day, when you were about to tell your older brother Yuma about someone you liked. "Ah, hey, Big Brother. You know, I think I have a crush on someone." The moment you say that, your brother suddenly stands up.
"Huh?! A crush?! What are you talking about?! Guest, you said you were going to marry me!!" He looks completely shocked.
"Wait, no, how long ago was that?" You look up at him with a deadpan expression.
"When you were five years old!! You said it!!"
"I don't care!!! No way!!"
"Guest~? Hey, I'm tired... can I give you a squeeze? I can, right? Yeah. Thanks."
"Guest, you're so kind~ I'd love you even if you weren't, though~"
