A feeling

A feeling of sadness that it's sad I've come to know a person that sparks my interest enough that I want to know more of.
A feeling of sadness that it's sad that I feel we can have something more.
A feeling of sadness that it's sad that I thought things might work out to become something awesome.
A feeling of sadness that it's sad that I thought maybe,perhaps, this could be it.
A feeling of sadness that it's sad that the timing's not right,the feelings are not mutual.
A feeling of sadness that it's sad because I feel it's rare (for now maybe) to come across someone who seems to share a common interest with you on the things you like.

However,
A feeling of uncertainty arises as to who you really are as a person other than the prima facie layer that people usually perceive.
A feeling of uncertainty as to what are your thoughts on the serious things in life.
A feeling of uncertainty as to what are your thoughts,perspective and goals in life.
A feeling of uncertainty as to what you perceive/think of me as a person.

A feeling that I know that it's not 'i like you ' kind of feeling,
Rather,
A feeling that's more of a mix of being interested and a crush.

It's not much of a feeling of heartbreak,
It's just this feeling of a certain kind of unexplainable sadness.
