They are all in their twenties; Asians don't have much facial hair and yes, they do wear makeup. Sets are built; probably just fronts. They almost never use green screens. They are fans of Bruno Mars and Anderson Paik, drummer, was featured on one of their live performances for their newest album.
This song was released in 2020, so they were ages from 23 to 28. This video was recorded during the pandemic, and this was a set, and there was a green screen for the sky and background. They only have 3 Fully English songs, this was the first one.
Of course they wear make-up in their MVs. Consider all the lights and cameras - their faces would disappear otherwise, every entertainer wears some make-up on camera. They are all gorgeous without it though. It's not their typical song, as it was created to cheer people up during the pandemic. They are not your typical K-pop group as they all are very involved in the creative process, their company grew having them as signed artists instead of calling all the shots from the start and on top of that they think of each other as family rather than group members. Their music varies and crosses many genres, they have a beautiful backstory as a group too. I would strongly suggest to react to one of the guide's - people won't stop asking you for this and you'll get why after seeing some of their history. Taylor Nakamoto's guide is the most current - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-huV_yIdxZPY.html - it's quite long but ARMYs (BTS fans) will be here for it and you won't even notice the lenght, every reactor says that.
