It might be just me but I see that the position, situation and roles of BTS members in their group are similar to that of f(x). The counterparts I have between the 2 groups go as:
- Amber: RM (Main rapper/English speaker)
- Luna: J-Hope (The 'vitamin' and one of the best dancers of their groups. Often overshadowed by the rest of the group)
- Sulli: V (Visual and 2nd youngest member)
- Krystal: Jungkook (The centre, visual and maknae. Both even have 'Jung' in their Korean name as Krystal's Korean name is Soojung)
As for the leftover BTS members, Jimin can be "Krystal" while Suga can be "Amber".
