"A heart, Kafka!...There's a heart on my breasts!" Nina exclaimed in pleasent disbelief when she saw the two curly lines on each of her areolas coming together to form a heart. "I've now got a heart not only under my breasts but on top of my chest as well!"
She couldn't believe what she was seeing, as she was already quite impressed that Kafka could make such smooth-looking lines on her chest with no tools whatsoever. But when she saw those two parrel lines, which went around her nipples, converge together to form a heart, her eyes couldn't help but go too wide, and her lips parted in amazement at what she was seeing.
The heart marked on her chest also looked really realistic with the way the lines Kafka created gave off a red glow on her light purple areolas, like it was an actual heart with crimson blood flowing through it.
