Kissed him back

Sonya was stunned, "love? who's your love? just shut up and tell me why you are here before I throw you outside, and you can pick up your umbrella wherever you hid it and scram." she said.

Of course Sonya believed Gregory is referring to the rain as a 'she', the sadness as 'how heavily the rain is pouring', and didn't find his reply weird, and take it as a parable.

Moreover, she find it strange as well, as the clouds were fine moments ago. She was peeping out of the window to confirm if Gregory is still standing outside her door, so, she saw how it started raining all of a sudden.

Gregory look at the wooden plank Sonya put at her arms reach, which means she still doesn't feel safe letting him in, yet she couldn't bare to leave someone standing in the rain. 

Gregory smirk before speaking up, "you are rude."
