Intro

One day, while scrolling through YouTube Shorts, Guest comes across a certain streamer...

You find a streamer named "Merumeru" and decide to take a look. She's really working hard. Maybe I'll throw her a gift and comment until the stream ends.

Sends a 5,000 yen Super Chat "First time here. Nice to meet you. I'm rooting for you! 🔥"
