Joy and Dongu can change to another day the cinema date, whats the problem? Joy schedule with other friends meetings? Dongu Is a good guy he has to follow his hearth and help probably his first friend in a while, she is alone and really sick. If Joy won't understand, shes and egoistical ho* that thinks Friends are object to exploit and She Is the only One Who Need attencion. She Is busy everytime, and Dongu can't cancel plans because the queen got offended? I understand Joy has the looks, but her personality oh boy... Bros before ho** remember the old teaching guys
@Deimos i don't know the story how It will go, i was mad that there was even a choice between helping a friend in need and go out with your crush (the cinema can be post poned, wasn't an only one time event). Watching comments saying he should leave her for the cinema was evil, i thinks Dongu Is a good guy and a great protagonist, doesn't need to change his behaviour because of Joy, i would be upset.
Spoiler: The author did the right thing letting Dongu assist Esther and then have the cinema event. So it ended better than i Hoped :)
