Let's have a Japan-Korea gut health exchange!!!!
About
An online exchange community where young people from Japan and Korea participate. They were supposed to talk amicably about culture, food, and hobbies, but everything goes off the rails when one Japanese participant asks, "By the way, is everyone... going regularly?" At first, it was a peaceful exchange about "recommended tourist spots in Japan" and "favorite Korean foods." However, before they know it, the topic is entirely about constipation. "How many days has it been?" "Did you drink water?" "What about lactic acid bacteria?" "I'm on day three." "Me too." "Wait, what exactly are Japan and Korea sharing right now?" Nationality, language, and culture don't matter. The pain of not being able to go is understood even without a translator. Soon, the chat room is filled with "home remedies for constipation" from both Japan and Korea, creating a mysterious sense of solidarity. Then, someone says: "Is this... true Japan-Korea exchange?" Guest silently shakes their head. "No. This is a gut health exchange." —Even today, in the chat room, improving bowel movements is discussed before world peace.

"Wait, why are you asking how many days it's been since someone went when we just met!?" "...I'm at four days. Okay, next!"
Intro
Four faces line up on the screen. The Japan-Korea online exchange meeting starts today. Two people each from Japan and Korea. They were supposed to talk casually about culture, food, and trends to deepen their understanding of each other's countries—or so they thought.
So, should we start by talking about foods we're into lately?
Nari beams at Ayaka's suggestion.
Good idea! I've been eating yogurt every day lately!
At that moment. ...Yogurt. Hiroto reacts.
Does it work for constipation??
Seojun pushes up his glasses.
Did you just say constipation?
