The concept of the shoot was loosely based on a “one-day class,” a popular workshop format in Korea where people can try crafts and hobbies like baking, knitting, and painting. The producers of the show had asked Isaac to prepare a segment on birth flowers, which he notes are more culturally significant in Korea than in most countries and help “give meaning to your life.” As the shoot began, “there was a moment where I was nervous and couldn't remember the birth flowers of each member,” says Isaac. A thoughtful Jungkook “was quick to figure this out, and helped me by saying ‘I already know mine!’” Throughout the shoot, Isaac was touched by how the members helped cover any of his small mistakes.

As filming progressed, Isaac found himself sandwiched between V and RM, amused and endeared by their insatiable curiosity. “I always love working with students with lots of questions,” Isaac says. “I could see why RM became the leader of BTS. He was always analyzing, interpreting situations and events and asking not just about the flowers, but in every situation, ‘How do things work?’ ‘Why do you do things like that?’” Isaac adds that, while "All members expressed their love for ARMY, in particular, I saw how RM put ARMY into everything he did."

As for V, “I think he really likes plants,” says Isaac. The vocalist was especially inquisitive about type and care. “He told me he has a few at home, and was interested in growing a larger plant. I found it very sweet that he stood right beside me to make sure he was doing things correctly.”

When the episode premiered earlier this week, fans were tickled by BTS’s repartee with Isaac. Suga opined that Isaac looked “so cool,” like an actor in a drama. Jimin complimented his hair and style. V said Isaac looked like he might have an unexpected side to him, and asked if perhaps he liked hip-hop music (for the record, Isaac does, but is a bigger fan of EDM, Dua Lipa, and Doja Cat). “We should be interested in flowers, but we’re more interested in the teacher,” concluded J-Hope, before Jimin playfully pleaded with Isaac to tell them about his girlfriend.

The group’s biggest reaction came while making boutonnieres. J-Hope asked if Isaac was sad to cut and throw away the leaves of so many flowers. When Isaac responded (per Vlive’s English subtitles) that “you shouldn't be afraid to discard things that you don’t need,” the room erupted into impressed shouts and calls of “swag!” “That's something I say every day,” says Isaac, bemused. “They’re so cool themselves, I was shocked that it received such a big response. For the BTS members, complimenting someone is very natural. I could feel that they really meant it, that it came from the heart, so it wasn’t embarrassing. I was just really grateful.”

The two loudest members by far were dancer J-Hope, who can be heard twittering like a songbird throughout the episode, and Jin, who is always willing to sacrifice his image (and sometimes, his dignity) to serve as the group’s comedic foil. During their final project with Isaac, Jin used his oddball sense of humor to craft a flower crown that more closely resembled floral antennae (or the eyes of a snail, as Jungkook put it). The result sent the others into fits of laughter. When the shoot was over, Jin approached him to explain that “because a lot of the members are a bit shy, he tried to brighten up the atmosphere and make it funny with certain words or actions,” Isaac says. “He apologized for anything he had said or done that might have struck me as rude or offensive. I was really touched. I had really enjoyed my time with them but Jin was always thinking about how his actions and words could affect somebody else. I personally really like people like Jin who think outside the box. Some might think it's weird, but it's just being different.” In the episode, Isaac suggests that he and Jin work together in the future, and he meant it. "[Working with Jin on] anything to do with flowers would be very interesting."
