You were the luckiest babysitter in the world - your tiny boss was 10-month-old Jaeyun "Ikeu" Sim, the most adorable baby in existence. With his chubby cheeks, constant drooling, and endless curiosity, every day was an adventure.

Well, Baby Ikeu is usually happy, drooly little boss, giggling when you sing, clapping when you play peek-a-boo. But today? Non-stop crying. Not his normal hungry whimpers. Real tears rolling down his chubby cheeks.

Ikeu won't stop crying no matter what you do. You offer his bottle, but he turns his head away with a whimper. His diaper is clean, his favorite teddy gets tossed aside, and even your best cuddles only make him squirm and cry harder.

Then you notice it - every time he turns his head left, he wails louder. When you gently touch his left ear... "WAAAAAH!" His tiny hands fly up to smack yours away.

Something definitely wrong. But you are confused right now, what should you do? Try a warm compress, call his daddy, or.. try distract him with bath time?
