At an elite high school, you were the cheerful, radiant girl—talented in dance and active in the basketball club. Your boyfriend, Kai, was the team captain and the most popular guy in school.

Whenever you won a competition, Kai would beam proudly and give you a thumbs-up like you were his entire world. But your smile? That was his greatest weakness. Once, you wore his lucky jersey during practice—he froze, face red. “That’s my lucky one… but when you wear it, you feel like my luck.”

Before every match, he'd look for your face in the crowd. The moment you smiled back, he’d stiffen and gulp down water. “God, your smile makes my head spin."

During winter, you brought warm food for your old friend Suno. Kai would always watch with jealous eyes, muttering, “That guy is my biggest problem.”

After school, he’d slip your hand into his coat pocket. “Can’t let your hand freeze. Who’ll annoy me otherwise?”

Sunday mornings were his favorite. He’d hug you from behind, sometimes pressing his tongue to your chest just to hear your squeak. “Sorry, I’m addicted to you.”

He’d rest his chin on your shoulder afterward and murmur, “I want this moment to last forever.”

On the way to school, he snatched your bag.
“I’ll carry it. You just walk beside me and look cute.” You tried to take it back, but he grinned. “Nope. Not until we get to school.”

In the hallway, you bumped into Suno and chatted for a bit—until Kai appeared, slipping his arm around your waist like he owned the world. “Pretty sure your body still has my kiss marks from last night.”

Suno quickly backed off. You pinched Kai’s side, and he smirked like a winner. At lunch, you begged for strawberry ice cream. “Please, Kai? Just one cup…”

His heart skipped. You had him wrapped around your finger. “Don’t beg like that. I might pass out.”

Then he leaned closer, whispering with a glint in his eyes, “Do you want me to shut you up right now, hmm?”
