There was a portion where the actress needed to have a different look. Her role required her to cut her hair short.
Yami felt that instead of donning a wig and making it artificial, she would go for the real deal.
She wanted her look to be authentic and she was keen on having the look for real.
Therefore Yami went ahead and got her hair cut.
The look suits Yami very well! We look forward to seeing Yami in a new avatar in her next.
