Yes, this is the re-written version of the story, I didn't like how I had written the first version, so I changed it to first person and added some more details etc.

Having grown up with Seungho as kids, Minseong supported him when he joined MBLAQ and quickly became friends with the guys.

Especially Mir. 

But now, when Mir sees Joon with his arms around her and his head on her shoulder, she knows she has to prove to him that it's him she loves, and not Joon.
