exist, suppose, be aware of, believe, feel
存 centers on the idea of something being present or maintained in mind or reality: existing, being aware of, believing, or feeling. The 'suppose' sense extends this as holding a thought as present.
存 is thought to combine 子 (child) with a reduced form of 才 (talent, ability), suggesting the idea of preserving or keeping something alive. The exact historical development is uncertain.
A child (子) under a protective roof-like top stroke: the child exists and is cared for, so you believe in its presence and feel its existence.
For ソン, imagine a son (ソン) who exists and believes in you: son -> ソン, and his presence makes you aware of his feelings.
