This "arc" starts with Taekseung not feeling worthy of Junyeon because he thinks he is not as good. To make him realize his worth the story chose to take Junyeon away and bring his brother who many times acted prejudiced to a possible partner to his brother. By having him fall in love maybe Taekseung will find that he is worthy and charming enough (he could charm them twice, since the brothers are so like). It's a really funny approach, and honestly I'm liking the brother and him together just as much.
