Eros told Selene everything including the exact words she said to Renz when she was drunk. She smacked her forehead after hearing Eros. She didn't know how she would explain this to Renz.
She said things that she was not supposed to say. She was worried that Renz might be thinking she's crazy and had lost her mind. She just hoped that her drunkenness would be enough alibi.
"I regret getting myself drunk. I promise I will not do it again," Selene mumbled to herself while rubbing her temples.
Eros bobbed his head frantically in agreement, patting her shoulder. 'Yeah, you should not. What if you will go kissing another handsome stranger when you get drunk.'
'Well if you will repeat it again, I don't mind being the stranger. I can just erase your memory,' Eros added to his thoughts, smiling cheekily.
