Aye can we also list relationships between the companies... :3
Nega Network and Loen Entertainment have ties because Sunny Hill used to be at Nega Network; Brown Eyed Girls members have made appearances in two of their MV teasers before so they are clearly cool... and Loen Entertainment manages Gain's solo career
Gain also appears to be close with JYP Entertainment - of course, she recently did the duet with JYP, but is also good friends with miss A's Jia and her We Got Married pairing Jokwon is from JYPE...
