L.Joe, the rapper of Teen Top is straight and he never thought of falling in love with a boy especially his other members (although he always found himself staring for a long time at Chunji, nope never).

During their fanmeeting for 'Missing' promotion, his fan (who was so obsessed with L.Joe) gave him three 'vitamin drink' cans and said he can get taller by drinking this kind of drink and she even stated that it happened to her. L.Joe who was happy with it thanked her many times and promised her that he will drink it before he goes to sleep.

Before goes to sleep, he keeps his promise and drink the vitamin drink that his fan gave to him earlier secretly hoping that he will get at least 4cm taller than he already was.

But what if everything going wrong? What if in the morning he found himself not growing taller but the opposite- he was turned to a 3 years old cute boy?
