(KPOPLINE) - This is the "fear" of many K-pop idols!
Idols have been trained for many years not only to improve their skills but also to improve their physical strength and endurance. Whether they're swamped with busy schedule, exhausting training, or just sleeping for 3-4 hours a day, it's hard to see them complaining or getting tired.
The hilarious moments of idols when being tickled
However, they'll definitely break when being tickled! Believe it or not, just such simple punishment is enough for these idols to throw their image away and beg for forgiveness!
Even the beautiful female idols....
...or handsome male idols can't bear this 'cruel' punishment.
