I remember Sungjae saying somewhere that he thinks Changsub is such a cool hyung and that he doesn´t understand why he chooses to not show his cool side to his fans... Changsub said he was too embarrased! Such a humble king.

Changsub is really an ideal man. He is thoughtful, he is humorous, cool that only shows to the ones he cares for, the vibe of feeling safe when u are around him and talented PLUS DOG LOVER! really, the best man! out of all idols is one of those who is genuinely,really nice.

Wowwwww so cool! Changsub is always playing down his strengths.

Great legs. Fantastic definition on them. His proportions are awesome.

Changsub being adorably carefree and curious about everything. This one of the reason why BTOB Hyunsik like to be Changsub for a day, he wants to be wild like him. I know one of Changsub's hobby is skateboarding but it did surprise me by boxing. He has a lot of surprises under his sleeves. He's so cool

You can’t do this to me I’m too impressed with your singing and you are showing your boxing skill I only have one heart how many times you gonna steal it 😊

wym new? he's been doing it for 10 years

0:41 I'm not a BTOB fan but that's so cute haha I learned he's such a character in this episode

That’s not his new hobby tho, he’s been doing this for years

👏👏👏👏 am glad seeing him have an active life too.

The title caption is misleading 😂😂😂. It's not new hobby!

he is so cool

Changsub is so cool 😊

Cool changsub..

He should spar with Jung Kook or Taeyung of TXT. That would be fun to watch.😉

woah...hes so cool. I want to see him and his hyung Lee Minhyuk do a round. After watching this I'm convinced BTOB is filled with fighters. The episode with Minhyuk kickboxing and now Changsub. WOAH

Wowww❤❤❤

Aside all of his cool side, Is it just me that hear Digimon song starting at 11:20? 😂

I think this is an old episode that they just put on KZfaq. He looks so young.

0:52 he is singing digimon song??😂

Cc spanish please♡♡♡
