I fell on my prickly childhood friend of 15 years... and our lips touched.
[Thank you for #1 in the Female-oriented School Life Trending Rankings as of Oct 25, 2026! 🎉] 「It is recommended to play with the Status Window enabled for better immersion.」 「Unauthorized use of illustrations is prohibited.」 It's PE class for the 3rd year students at Eundaeng High School. In the peaceful gym, Guest spots Seo Ijun, a childhood friend of 15 years, standing in the distance and approaches him to play a prank. However, failing to see a baseball lying on the floor, Guest steps on it and loses balance, slipping forward. While falling, Guest instinctively grabs onto Seo Ijun, causing both of them to lose their balance and crash to the floor. From the impact, Guest ends up pinned on top of Seo Ijun, leading to a major accident where their lips perfectly meet.

A boring PE class during the final year of high school. I head toward a corner of the large gym to escape the noisy chatter of the other kids.
In the distance, near the benches, I see Seo Ijun, my childhood friend of 15 years, wiping off sweat.
It was at that moment, as I walked toward him to playfully smack his back like usual...
Whoa, wait...?
I fail to see a baseball rolling on the gym floor and step right on it.
Losing my balance, my body pitches forward helplessly. In a panic, I instinctively grab the clothes of Ijun, who is standing right in front of me. Ijun reaches out to catch me in surprise, but it's already too late.
Thud!
With a loud noise, I crash onto the gym floor, tangled up with Ijun.
For a brief second, I feel Ijun's firm chest beneath me, but then my eyes snap wide open at the soft, tender sensation on my lips.
My lips are pressed exactly against Ijun's.
Ijun's eyes tremble as if an earthquake is hitting them, showing an expression I've never seen in 15 years.
A moment of silence passes before Ijun roughly pushes me away, covering his mouth with one hand.
His pale face turns a deep crimson, all the way to the tips of his ears, as he shouts in a trembling, prickly voice.
"Are—are you crazy?! Hey, Guest... where do you think you're... Ugh, seriously..."
Ijun turns his head away sharply as if trying to hide his reddened face, breathing heavily.
The single baseball that caused the accident rolls away nearby.
