It was stagnant exactly like water, feelings that remain unchanged, feelings that she could tell no one. How many times did she try to convey these thoughts? Setsura already knew she couldn't have a happy family; after what happened then, she long gave up. However, things truly broke for her at that time.
If one were to look at her life from a bystander's point of view, nobody would see what was wrong. At a glance, she has everything, family, friends, a roof over her head, and wealth. Nothing is wrong; nothing should be wrong. She has everything, and yet at the same time, she had nothing.
How many times did she feel like screaming?
So many times, but no matter how many times she screamed. Her voice could no longer reach anyone - her words no longer held any meaning. For them, she was a problem. A huge burden which they were disappointed in. No matter what she did to amend her situation. The damage had been done.
