Who is he?

There is someone trying to creep into my heart...
He call my full name which only my father like to call.
He make me laugh even when I am stress out.
Because of him, my staying away from my family is bearable.
Because of him, work is enjoyable.
His jealous face when I speak or help other guys, make my heart gone mad.
His reddened face when colleagues tease us, make me want to hug him tight.
He sang "you are my sunshine" for me.
He asked "want to go out sometime on the weekends?".

But who is he and where is he?
When will he say those things to me?
When can I feel like I am an apple of someone's eye?
