[UNEDITED]
While everyone was busy with work and things going on with the country, Kimmy took her time to have a day off and spend it with her mother. She realized that Cain was right. She should check on her mother and spend time with her after being gone for a long time.
She was inside the car, thinking of ways she could avoid Cain.
'Why would you avoid him?! It's not like you are committing a mistake! Why are you feeling shy when he is so shameless? You're so affected! You can always reject him!'
Yeah, she could reject his advances, but she was doing nothing because she could not stop her body from reacting positively on its own. She could not trust her body at all. She was still doubtful of Cain's intention. She wronged him and his family, so what if it was some revenge where he would only make her fall for him then later do the same thing on her, leaving her out of the blue afterward.
