Sigrid curled her lips in dissatisfaction. A frown crept into her face, and she willed herself to stay silent.
The other guys seemed to have found a way to help them distinguish their partners, so they started to check out the women's hairline carefully. However, Natasha had already thought of this in advance. Thus, except for Sigrid and Elizabeth, whose hairline looked particularly nice, the others had applied thick hair shadow to beautify their hairline which would also slightly alter the appearance of their face shapes.
Natasha only missed Sigrid's hairline because it looked to be perfect at a glance, with only a small area of her scalp with lesser hair.
Natasha suspected that George had trypophobia, which is why he was more afraid of looking at the areas on her head with more hair than he was with the area with lesser hair. This was how he managed to notice the difference.
