Hmmmmmm....seeing how friendly and likeable LSS is behind the scene there shouldn't be a problem with her getting along with anybody, and I think she's far from being untouchable according to the BTS pictures. She just click and have more in common with actor/actresses around her own age (Ma Tianyu and Yang Mi as evidence), same goes for Ruby. Ruby and Peter are a decade older than LSS, and Wallace is 8 years older. It's only natural you click with your own generation....my opinion
