THEORY #1 : DREAM ???????
IK THIS IS EARLY BEFORE THE BACKSTORY BUTTT
basically we all know Dream is a holy person. what if it was all an act? i mean, she didn't became friends with other perverts like Yamoha so it doesn't ruin her appearance. But that doesn't mean she is very holy. According to Dream in my sister priv acc on insta comic vol.1 chapter 38 on 4th slide, she said "I was force to do everything for people on outside the castle in Heavell *sigh*" this were prove that before she got adopted by the Heavell king, the scientist(?) force her to not act childish.
2. According to Dream, she said "i never had a real name" this proves why she allowed people to call her everything they want. "i always forgot people's first name*sob*" probably why she calls everyone 'darling'/'sweetheart'/'dear' in language people speak.
DONT ASK HOW MANY SCROLLS I TOOK FOR THIS
