After School's leader Kahi finally opened up about rumors that her and singer Seo In Young do not have a good relationship. On September 28th, Kahi wrote on her Twitter, "I'm on bad terms with Seo In Young?! We got closer~ The more I get to know her, the more she's my favorite child Seo In Young." Kahi also uploaded two pictures of them together. The two took pictures of them wearing the same hooded sweater, with both their hands in their pockets. In one picture they posed primly, while in the other photo they smile as they look at each other. The rumors arose when the two were both cast for SBS's 'Heroes', where they showed an awkward relationship on set. Because Kahi is 4 years older than Seo In Young, but debuted much later than her, the two did not know how to talk to each other. As the show continued on, viewers started to notice this awkward relationship, which was when rumors started to develop. After persistent rumors, Kahi decided to step up and show evidence that the two are in fact quite close. Fans who saw the picture replied with, "Even your stubborn expression looks alright", "After watching Heroes, I realized Seo In Young has a cute side too. I was a bit surprised to be honest", "Everybody let's stop the rumors now." Source: Newsen Photo: Kahi's Twitter
