Don't know how tertiary environment is like.
Fake ah... fake or not hmmm... in JCs, I would suppose socializing
is a very important thing (unless you're the kind who studies all
day and doesn't give a single damn about the rest).
I've never heard of the "girl getting involved to spite another
guy" thing though.
Maybe in JC, students are more care-less, more passionate about
enjoying life than having other concerns... love is all around!

Don't know lah.
