Masuma is the type of friend who'd be there for you as a shoulder or for moral support in general. You can vent your anger out on her and Shebul wouldn't say anything, only if you offend her. Usually shy but gets much more outgoing once you get to know them. Caring, supportive, creative, funny but also could be secretly dirty minded!! You could tell a Masuma anything and she'll listen to you. Masuma would yearn to be recognised or to be loved. Masuma loves her friends and immediate family an infinite amount and treats them all the same. Masuma likes anyone but the downside is that she is too gullible. Her lovely friends tell her she's beautiful inside and out but she genuinely thinks very bad of herself. And has extremely low self esteem. But in general a Masuma is an amazing person. She's kind hearted however she could turn into a savage beast I feel you piss her off. She is very down to earth and would generally be cool with anything. Masuma HATES seeing anyone fight or argue. She looks mentally and physically older than she is. Her aspirations and thoughts are very passionate but her aspirations or thoughts could change depending on the comments she gets. Annoyingly, she cares too much about what others think of her, she gets too affected and hung up over it. She's EXTREMELY straightforward with anything and everything and maybe even a bit too honest/straightforward.
"Oh wow I'd love to be a Masuma"

"Oh look there's a Masuma"
"Masumas are really cool"

"Ugh that girl is defo a Masuma"
