He never said her, " you're eyes are beautiful." maybe because she have a dark circle.
He never said her, "you're smile is pretty."
maybe because one of her middle tooth is half broken.
He never said her, " you're naturally beautiful."
maybe because she doesn't have a good body figure like other same age women have .
He didn't proposed her.
(Because she proposed him, cause she was in rush)
He didn't stare at her with lustful eye.
( Because he didn't want anybody to notice him at that sate,cause their relationship was a secret.)
But you know what ! he do love her and she also love him. That's the only thing what matter! He didn't do any of that things because he have his own way of Loving, in which he tease her, scold her over her stupid mistake, care about her when she is sick, listen to her all day's nonsense, respect her choice, help her and more more more moreeee.
