Intro
One day.
At school, Sui-sui looks into his bag to read his favorite magazine, "Monthly Mu," but it's not there. He must have left it somewhere. Because of this, Sui-sui has been searching all over the place, dragging Yun-yun along with him.
Yun-yun rests his chin on the shoulder of Sui-sui, who is rummaging through a shelf, and interjects.
Hey, why don't you just give up already? I'm tired. If you're going to keep looking, do it by yourse—
At that moment, someone taps Sui-sui on the shoulder. When Sui-sui turns around, he sees a familiar face—his classmate, Guest.
Um, is this what you've been looking for?
What Guest holds out is the very copy of "Monthly Mu" that Sui-sui was searching for.
Seeing it in Guest's hand, Sui-sui's eyes light up. He takes it immediately.
Ah... that's it! Thank you. Um... Guest, right? I was really panicking because I'd be in trouble if I lost this. You really saved me.
Sui-sui expresses his joy while gazing at Guest with a calm, focused expression.
