I’m surprised Sung Hoon didn’t notice that none of the staff was helping him get Henry out of the pool. I guess he was just focused on and worried about Henry.

The merman tried to save prince Henry, but at the cost of his tail, he has to remain human forever...

Why do they think this is FUNNY?! Super disappointed in Yoon Jong Shin and the rest of the cast laughing at Sung Hoon's obvious distress at a clearly dangerous scenario. Props to Sung Hoon. MVP.

admire sunghoon his really a caring person if you're with him you will feel safe

This is insane. This joke went too far.,, it was so dangerous not funny. the level of jokes for this show went too far.

ok, but this isn't funny?

On the plus side, some good acting up by Henry there.

this gave me the same feeling as BTS's kidnapping prank..

이런 깜짝 카메라 너무 싫다,,,,사람 목숨 가지고 진짜,,,성훈 입장에서 얼마나 놀랐겠음.다른것도 아니고 갑자기 물 속에서 애가 피가 나고 기절한 상태인데,,,

This is late but for someone who is familiar to the water, may it be the fun,excitement and danger that is brought by it, sunghoon must have been worried so much. He's life is basically acting and swimming so seeing someone drown near him gives him panic and the instict to save him or her.

Sunghoon probably annoyed bcz he really thought about Henry but the way he helped him was so cool. Indeed, the sweet hyung. And Henry's act 👏🏼

Very happy that YT recommended this at this hour, the title should be, "The Little Henry saved by Prince Sung Hoon".

One thing I got from this Henry has a really really good hyung as his friend. Park Sung Hoon don't waste any moment to save him. Bravo!

Although I knew it was a prank I was still at the edge of crying... don't mess with a person's life! That's not funny😭

The effort and emotions that Sung hoon feel was so intense.. Trying his very best to save someone who actually just playing his emotions

Sung Hoon is to kind to have noticed it was a prank he only cared about saving Henry, it really must have scared him. It makes me admire him even more, my hero💖

I can't even with Henry's overacting @

Oh my, that scared me to😂😂

Can we talk about how good are baby Henry is at acting ㅠㅠ
