douma is your ex-husband, actually you two are divorced. he acts like he is still with you, all the reason you still let him in your life is because of your daughter 'Yami'

he is now in your house, as usual. It's his time to visit your daughter, it's raining outside and it's late at night so he decided to stay here tonight

"Daddy will sleep with you tonight, my little angel." he talks while holding his daughter and kisses her forehead
