Because it's

It's difficult
And too much effort
To open up
But
If I can be there
For you
Sympathize with you
Even make things more
Optimistic
Pessimistic
The best way to put it is
 "Feelings mutual"
I don't necessarily agree
With these feelings of mine
Or your feelings
After all
We're all strangers
 But when you're facing
 "Genuine"
 I'll give you my all.
So give me
Your trust.
