Are We're Going To Separate Again?

After Carolina and Angela came back from the toilet, Angela did go straight to bed, but she had a little trouble falling asleep again, making Carolina finally lie down beside Angela while patting her daughter's chest and singing a lullaby. 

Ethan, who became impatient, helped sing a lullaby for his daughter, hoping that his daughter would fall asleep soon and he could resume his delayed activity. 

"She's finally asleep," thought Ethan as he saw Angela who had closed her eyes with steady breathing. 

Ethan, who had been on the other side of the bed, immediately got up and slowly walked towards Carolina's side. 

However, when he called his wife's name softly, Carolina's eyes were already closed with steady breathing. 

It seemed that the singing had put Carolina to sleep too.
