I strongly believe all their solos opportunities/popularity came after Queendok, iv been looking bk at their vlives/fancams from festivals/non music show performances n i believe gp has always loved OMG(in korea at least), just tat Queendom raised their profile n brand to advertisers/producers/tv stations n such tat they got more popular/opportunities after tat. Hyojung was responsible for the eottoke song previously but nobody rlly noticed tat earlier i think. Sseung is a rlly great singer but this yr i think she's blown up a lot n gotten a fried chicken cf tats hilarious, im not sure when Nene Chicken started using OMG in promos but i think it ended before Querndom. Arin, Binnie, Mimi n Jiho were kinda under-valued b4 Queendom as well i think. YooA is kinda an exception but she also blew up in her profile n branding i think after Queendom. If im wrong, ill admit it but i think OMG just dint hv viral luck previously like Gfriend Yuju n Twice Sana Sha Sha Sha tat blew them out of the stratosphere(with Twice, i concede it was inevitable after Sixteen n either Tzuyu, Nayeon or someone else could hv been it). I think Gfriend rocketed upwards but couldnt sustain smh.n slowly been falling bk to earth(but i love them n dont agree bighit ruined them, i think it was happening anyway long before bighit buy-in, i dont agree musically they deteriorated either-im only talking abt sales/popularity not musicality/artistry, i love their stuff still).
So i hope OMG sustain their rise for next 5 yrs which is abt wat i think Gfriend lasted from their burst since Yuju went viral n propelled them to 3rd gen top 5 status (imo). You r free to disagree ofc.
PS: Lovelyz n Bom dint get much rise from Queendom, imo n the others were already high up tat it dint make much difference(AOA, MMM, GIDLE). Again imo, n u may disagree. Did u watch good girl, ozy? Whole nother story there, i think(similar effect, imo)
