Brain-teaser

Bold enough to tolerate my childishness,

avenger of my loneliness

rude! Oh! No, he is not.

understanding! Yes of course.

nothing shall be comparable to his love,

trusting him is what I can do with my eyes shut

already the king of my heart,

momentarily may be; with him, I can't depart

running, I go to him

anywhere either in the reality or let it be the dream

kindly he returns to where I am

as he too can't stay without holding my hand

Rumors about us are already on now.

Hint; They say he is the man of vow. 

Here is a brain-teaser for you.

Find out, Who is he?
