User blog comment:Leon Jung/What do you guys think about Selina?/@comment-23815366-20140520112933/@comment-27111026-20140520125642

To me, if my friend is much more popular than me, people love her and such, I'll be happy for her, sad and jealous -- of course... but I don't really think about hurting her... because, after all, we're friends, right?

So I believe there should be a reason behind this as Selina did mention that Acheron is the "only friend" she has.
