Her elder sister really had stupid brain compared to her little sister who had smart thinking and logical for not accepting his smart mouthed invitation.
Looks like I was right from the moment they meet in previous chapters, Lin Feng already know that it was just a setup from the beginning and he dont want to interfere since he know that young master just seeking beautiful ladies to fall in his grasp and soiled them then throw them like a garbage.
Man, is she (elder sister) really an idiot to trust someone who she doesnt know at all because of his 'good' acting???
No wonder her elder sister is rubbish compared to her younger sister who had wise thinking and never let her guard down from this kind of soap acting.
