Jaeyoon knows Inseong's limits. He really encouraged him

The way inseong has shot so many videos b4 he went for us . It's the warmest feeling ever . It feels like he genuinely cares about us😭😭

Seeing Inseong in gym is like 8th Wonder for fantasy. A long awaited video

This is what I mean when I say JaeSeong are soulmates. They compliment each other in everything and here we can see Jaeyoon really supporting Inseong genuinely and he doesn't want him to get hurt.

my god! is this jaeseong’s way of celebrating pride month

Jaeyoon : your shoulders have gotten wider Inseong : wow I can't get into an elevator Jaeyoon : *ignores* 😂😂

Jaeyoon can be a great and patient gym trainer heheheh

Inseong never liked working out much but he was unexpectedly good and cute at same time 😭✊

when it's jaeyoon and inseong together in a room you know its gonna be legendary jaeyoon did so well as a trainer with the constant shower of compliments. i wish i had a instructor like him. plus got looks and physical. and Inseong is so good in everything including PT been proved today. cant wait to see inseong who won't fit in an elevator and I loved how you both still found a way to bring up fantasy into the conversation.

First off all: thanks to Inseong & Jaeyoon, staff with the cameras & in the mirrors, translators and everybody who contributed in that content making! ❤️ That's one of the best things I saw recently, and with subtitles already! ❤️ About video: aaaaaaaaah! ~ I don't know where to start. If I went to the gym and my personal trainer was Jaeyoon... I would either pass out at the entrance or pull up that 80 kg without noticing... But I would be very concerned, because exercising & seeing Jaeyoon at the same time is really too much for my heart. 😂 Anyway - at the beggining I thought to myself: "Oh, I had exercising in my plans anyway - maybe I will do that today at home". But then I understood I would probably have enough after the very first warm up. 😂 Inseong did it very good, I am impressed! ❤️ When he finished - everything was hurtung me mentally like I was exercising myself, haha. But he made all that with such a cute face in a such a positive manner. It was nice to hear the stories about SF9's daily work out routines. I want to work out too, but I am a little bit scared. 😂💪🏻

Inseong has vocal, visual, personality he has everything he's so perfect and most importantly dancing,

I see a real man keeps his promise to overcome every challenge and go beyond the limits. This is our Megastar, *Kim In Seong* ! 🤩💗

OMG with subs finally. I miss him :”(. Three months since he left to military and he already drop 3 videos. Wait 21 months 21 video. I am in tears :”). he really thinks us fantasy :')))

i'm a new fans of SF9..... i like this boys group somuch

My monthly happiness. This made me giggle so many times. Inseong really impressed me with his ability as well. Thank you Inseong and Jaeyoon for making this for us. 🤗💕🌌
