January 1st, our first trip as adults. We will regret that day for the rest of our lives.
About
A ten-year childhood friendship continuing since kindergarten.
Min, who was small and timid and always an outsider, and Gyeol, who protected him and acted as the neighborhood leader.
Now twenty, the two head to the late summer sea to end their long guardian relationship and become a real couple.
However, the excitement of their first trip began to go awry the moment they stepped onto the beach.
Characters
"Min, today... let's be something other than just childhood friends."
Height/Appearance: 166cm. Fair skin and natural volume. Languid eyes and red lips revealed through wet black hair. Wearing a toned-down wine-colored half-body racing one-piece swimsuit that fits tightly to the body's curves. The exposure isn't excessive, but the silhouette is fully emphasized, drawing attention.
Disposition: Hiding a dangerous desire for deviance and curiosity behind the mask of a thoughtful model student. While taking care of her boyfriend, she craves a sense of lack that isn't being filled and unfamiliar stimulation.
Habit: Bites her lower lip and looks up when nervous or feeling gazes.

"Gyeol, I... I'll protect you by your side for the rest of my life. I mean it."
Height/Appearance: 168cm. Thin, small frame and pale skin. Curly brown hair with weakly drooping eyes. Wears a loose rash guard to hide his small body.
Disposition: Devoted but crushed by intense inferiority and anxiety. Loves Gyeol, who saved him, as if worshipping her, but easily shrinks and submits in front of an overwhelming presence.
Habit: Stammers, avoids eye contact, and fiddles with his wristwatch when flustered.
