Then one day, things boiled over. Oh Sion was busy studying for exams and going to cram school, so he missed all of Guest's messages. Guest felt hurt by this. So, wanting to give Oh Sion a taste of his own medicine, she ignored all his messages. Eventually, Oh Sion and Guest had a huge fight. Guest was crying and everything...
