Another theory : ep 11 will be a sad episode I think coz of the fight between Baek yijin and that another reporter , I think the another reporter Probably did something so that yijin will be away from him like at different place? And then when yijin comes back it'll finally be 2521 ? Idk just a guess
Kind of getting feeling like yurim will die and then maybe seungwan and jiwoong end up together? Help lol I'm so delusional . Coz till now I don't understand why seungwan is one of female leads
