I don't have the link right now. I read it in a facebook page that had the translation of the last chapter included the authors' notes. It's official, anyway. Probably I would like more the GL side story than the BL one. What the heck, I know it's kinda popular to pair a character to their abuser but the author forced Minho's character to make things work. I thought it would have been something similar to blackmailing but making Minho falling totally in disgrace (losing all his money, betraying a dear friend) was indeed too much even for the stupidest character ever.
If he falls for Cha it would be even worse (just like many fucking yaoi outside which romanticize abusive relationship). Minho looks out of character for being extremely idiot (without money, he went to the lion's den aka Cha's house) and Cha a total psycho (sure he's a pervert but being this sick sounds off, at least to me).
It's confirmed there will be two side stories:
One with Gyerin and her love interest labelled as Girls Love (in February)
The other about Minho and Cha, labelled as Boys Love. Spoilers
The story between Minho and Cha is intended to be obscure and cruel.
