At first, Tanaga's reason for kissing Ashley was to punish her for biting his palm. However, once he tasted Ashley's sweet lips, he lost all his senses and he gave it all with his kiss. It would have been alright, and everything was going accordingly. The honeymoon begins...
However, it's because of the amount of alcohol that Ashley had drunk... She suddenly felt nauseous and about to vomit. So she quickly pushed Tanaga away and ran to the bathroom like the grim reaper was after her soul. She was leaving Tanaga's shocked face to just follow with his gaze.
Tanaga was still shocked at what happened and unable to speak when Ashley pushed him away. He only stood there rooted to the ground with a blank look on his face. He's not sure if he would get angry or just let her go. This is absurd and continuously happening every time they try to make out.
