Kpop concerts in the o2 forum london

Has anyone gone to a kpop concert in the o2 kentish town? What's the queue situation like? I have general admission and have absolutely zero interest in trying to get close to the stage or anything, but with any other artists I usually rock up around the time doors open or a bit after and can get straight in but all the kpop gigs I've been to apart from jinki in paris the queues are pretty long and I dont really want to stand in the rain for too long if I can avoid it 😅
