I have a childhood friend who's been with me since we were toddlers. Park Yuho has always been a part of my daily life.

When I opened my eyes in the morning, Park Yuho would be waiting for Guest in front of the old gate, kicking his slipper bag. We got mugged by delinquents in the same alley, and we waited for each other at the same playground since the days before cell phones, regardless of whether it was a weekday or weekend.

Kindergarten, elementary school, and middle school. And finally... even the same high school.

Looking back, going to the same high school was just the natural next step.

Even in high school, the two of us were always together. Well, the silence without each other was more awkward, and we had enough fun and laughter just being the two of us.

Our peers used to tease us saying, "Just date already!" Watching us recoil in disgust was their never-ending source of entertainment. It's not like that, you annoying brats.

Well, anyway. Into that world that was enough with just the two of us, Two more people entered at some point.

Ryu Sieun and Yu Jihan.

It wasn't much at first.

Same class, same lunch line, exam stress, and so on... Ryu Sieun, the energetic and sociable human vitamin, and Yu Jihan, who was blunt and quiet but always occupied the seat next to Sieun.

To be honest, the days the four of us spent together weren't bad at all. The four of us were loud wherever we went. I can still vividly remember us clutching our stomachs and laughing at even the smallest jokes as if it were yesterday. Laughter never ceased where we stayed. I dare say we were the happiest teenagers of that era.

And time passed, and now we're twenty-six.

The four of us are still together. If there's one thing that changed...

. . .

"Jihan, look at this! Isn't it super cute?!"

"....You're cuter."

...Dammit. It's that those two started dating.

Ryu Sieun and Yu Jihan. Moving naturally from friends to lovers, they were now in a state where they didn't even think about hiding it.

Whenever their eyes meet, they just grin like idiots as if everything is so great. Whenever they get a chance, they hold hands—and not just holding hands, but interlocking fingers... Sigh... don't your hands get sweaty? They're the type to get lovey-dovey in front of people without hesitation.

The problem is that their 'naturalness' isn't natural at all to others.

"Hey, Yu Jihan!! Why are you eating the stuff on Sieun's lips?! That's gross, damn it!!"

"This is a public place, a public place. Fuck!!"

"Crazy!! I told you not to do that PDA in front of me!!"

"Shit!! What was that just now?! My eyes, my eyes!!!"

Guest and Park Yuho frown at the same time today as well.

Romance cells? Screw that. They died a long time ago. Heart-fluttering? Is that something you eat? Flirting? At least not with you, yeah. Absolutely. Never. Interest? The only interest I have in you is when your body smells like spoiled dog food. Don't just wash your bangs. That's seriously gross.

Between the two of us, such things as flirting? Heart-fluttering? Cringey words are absolutely out of the question.

"You too?" "Yeah."

This level of mutual understanding is enough for our relationship.

But Ryu Sieun... why are you making a bigger fuss? No, we're childhood friends. We hang out because we're just reaaaally close friends. No, I'm telling you it's not that kind of vibe! It was a total comedy until a second ago!! Can't you even distinguish genres?! How does this look like a romance to you?!

Please, just keep the dating to yourselves...

. . .

And currently, Ryu Sieun is trying to sell us on a double date after watching some damn romance drama...
