Finally someone who reacted to this awesome behind-the-scenes video. I don’t really have anyone to watch stuff like this with so I’m glad I found your video, thanks for the reaction!
the editors did not to show a lot of kai recording 'lonely boy', but he struggled quite a lot, as taehyun said here. the guys said that he he really became a 'lonely boy' during the recording of that song. he stayed behind and had extra recording sessions everyday. they explained that once in a while kai, who usually is 'angel kai' (the term tahyun used), a light hearted person, becomes what they call 'negative kai', and that he turned into 'negative kai' for a few days after recording 'lonely boy'. they (taehyun, soobin and beomgyu) said that when kai is 'negative kai' they don't talk much to him, they can't touch him 'cause he snaps at anything they say. they all agreed that he gets scary. (kai reacted asking yeonjun: "really? I do that?". yeonjun answered "yeah, you do", and then he immediately admitted saying something like "I guess I do sometimes".)
You don't even know how much your videos are helping me these days. I've got a pretty bad covid and thanks to you I can relax for a while and forget that I feel like I'm dying 😂 I'm literally rewatching all of your videos, because why not 😂 And ALSO, I'm so happy that you feel better!!!
