"Please let me stay a little longer" 

  An umbrella exchanged late in the night is the only tie a famous idol and broke uni student have and they're set on not breaking it. 

 Yumi's broke. Like many fans, she supports her favorite group, EXO, as much as she can but knows she'll never meet them. Or so she thought. On a bus ride home, she meets her favorite member Jongdae and two others. Not wanting to be seen, the two form a bond to keep the boy's identity hidden, as a way of thanking her Jongdae gives her an umbrella and disappears into the night. Thinking it was a dream Yumi wakes up the next day and can't believe her eyes when she realises the umbrella she carries is the same one from that night. 

Will she be able to give it back to the rightful owner?
