@Aeriandra "These two are so cute! looking forward to getting some more backstory. I know I'm probably completely off, but for some reason I get the feeling like the blonde sunbae could be the sister's stalker. Maybe an elaborate plan to make her feel uncomfortable and more receptive to a guy sweeping into help her all the while the sunbae everyone hates automatically takes the blame.
@Siquall "So, someone was still keeping these two away even one year before huh. Same as the glasses girl, there was probably one (or several) guy who was jealous of their relationship.
