Through the reshaping of the body by the soul, one's appearance can be crafted according to personal desire.

All these days, Seraphina's soul had done nothing else but design her appearance and physique. 

Based on her previous interactions with William, she discovered that he seemed to prefer cute girls, and then she took inspiration from Alice's figure.

She also gathered some insights into individual men's preferences through Sofia.

The conclusion she reached was that William, a mature man who has lived for many years, probably favored flat-chested, cute girls.

There were even online discussions suggesting that such girls possess major traits: a soft voice, a supple body, and being easy to get into bed with.

So, Seraphina's current form was the epitome of light and soft-bodied, with an added touch of cuteness. Being so proactive, she embodied the three major traits of this type of girl to the fullest.
