Introvert but loyal
Always keep mouth shut yet talkative when the right person came.
Socialize but selective
Enjoying befriend with anyone yet loyal with someone.
Boring but creative
Might be lame yet full of surprise
Lazy but diligent
Unmotivated to do something for the start yet enthusiastic along the progress
Plain-looking but metrosexual
Unattractive yet really into self-grooming
Simple but perfectionist
Straightforward yet demanding
