Welcome!
Although, I gotta ask: Shi-Shi? (you brought it up, don't look at me!)
Haha. Well Cerese is my middle name and some people call me that. Then those people started to shorten it to Cece.
But then when my baby cousins overheard their older siblings calling me "Cece," they tried to imitate the sound.
And it came out as "Shi-Shi."

Since then, some family and even some of my friends started to call me "Shi-Shi" because it sounds adorable. Lol.
