Who should get married first?

''I would get married first''. 

''No! I would get married first''. 

Grandpa Lee, Grandpa Xi, Lee Kwan and Kim Ara were sitting in the living room watching Lee Rang and Roger fighting  for the last one hour. One week had passed since Elder Lee announced Lee Rang and Yuri's engagement and Grandpa Xi together with elder Lee announced Roger and Suyan's wedding date. Since then, Lee Rang was fighting with the elder's and Roger that he had the right to get married first but Roger was not agreeing with it.

''Stop you both''. Elder Lee finally spoke. 

Roger and Lee Rang looked at him and then both lowered their gazes because they sensed grandpa was angry. 

''Lee Rang! We would get you married right after Roger's wedding. So what's the problem?'' Lee Kwan asked.

''Aunt, I started dating first and it's my right to get married first''. Lee Rang replied.
