I have a feeling Jennie has some sort of condition or disease. She probably got it after as if its ur last. Notice how after that comeback she's been lacking a lot of energy ( the lazy scandal and stuff). She's been more lively in performances now but she aint the same. Remember the 2016 gayo daejun, idk how to spell it. She was so fucking charismatic. Like she aint that anymore. And she also looks the most out of breath after a performance. Also notice how the choreographies have kinda gotten easier ish since aiiyl. And maybe also why she doesnt rap as much anymore. Like theres literally no reason why they cldnt hv a jennie rap. she spits fire. Maybe she gets more breathless when rapping? So i feel like that theres more to it than we know. But i think theres defo smtg up with her. I dont think its depression or anything cuz wld depression affevt ur stamina and breath control. im not too sure but imo idts.
