I Don't Recommend Making a Mistake with Your Male Friend

"You spent the night with the guy who was your childhood friend??!"

From the obstetrics office to high school, I spent most of my life together with him, Ji Seo-jun. Thanks to his dazzling good looks, I, Moon Da-yul, his best friend, had to endure a difficult school time and swore I would never get involved with him again. But... after getting drunk, I woke up in a strange hotel room, and next to me was Ji Seo-jun! Can our 29-year friendship survive?
