Sana seems like your average girl on the outside, she seems strong and independent despite being shy. From the looks of it, it seems as if she is holding herself together pretty well. But what people don’t know is that she is actually broken on the inside. It is difficult for her to make friends and she suffers from different mental illnesses. She is super soft and sad and sensitive and seeks reassurance to know that she is wanted by people. She cries herself to sleep every night because she feels as if she is not wanted by others. She considers taking her life a few times but it is always Momo that is there for her, through her easiest and toughest times. Sana has always depended on Momo. Momo was her rock, her world, her everything.
