First of all i love Haseul to death, this is NOT a drag this is just something that have been at the back of my mind. I feel like Hyunjin fits ARTMS vibe and concept more than Haseul, plus the chemistry between Heejin Hyunjin is unmatched. Also it fits their lore about Hyunjin and Choerry, and she definitely has that classy elegant vibe that all other ARTMS girls exude. Dont get me wrong, Haseul definitely fits ARTMS concept and chemistry but i feel like fits Loossemble better.
Haseul fits Loossemble concept more i think because of her pure vibe, and Haseul Yeojin mother-daughter relationship is unreal. Haseul would also bump their Loossemble's vocal as a whole since her vocal was always underutilised (and probably would still be overshadowed even under ARTMS), thus relieving Hyunjin of carrying their vocal department.
Haseul is NOT too old to fit Loossemble, i mean Vivi is literally there so age is not an excuse. Haseul also have 0 lines, 0 screentime and 0 center time in LOONA despite being one of LOONA's top vocalist, which is also the same fate that befell other Loossemble members. Haseul being in Loossemble would be a godsent to them because they definitely need a vocalist (im not saying they cant improve but Haseul would be a great addition). Haseul also love to sing and having Haseul to carry their complex vocal would be a gift to her and to us orbits.
i love ARTMS and im so excited to see them because ARTMS consist of only the best vocalist and vocal color from LOONA, and they have also the best vocal dynamic in the entire 4th / 5th gen industry. Haseul entering ARTMS is a bliss because she strengthened their already strong vocal line. however even if Hyunjin and Haseul were to be swapped, Hyunjin would still be able to vocally hold her own weight in ARTMS and Haseul would be a great help in Loossemble. I think it all worked out to both groups; Hyunjin definitely fits ARTMS concept and Haseul would be the best vocalist in Loossemble.
Im very much satisfied with both group's current lineup but this is just a random thought lol. What do you guys think ?
