Our temperature!

Yujeong has an extremely active body temperature and as a result, she becomes too hot during sexual encounters to fully enjoy the experience. Ultimately, this desire not being met causes her to break up with her boyfriend. Fast forward several years later, she attends her high school reunion and runs into an old childhood friend named Han Seo. Unlike Yujeong, he has a much lower internal body temperature. When Yujeong and Han Seo touch each other, there is an instant chemistry and before long, they find themselves in bed together. However, where do things go from here? When they both become aware of their contrasting temperatures & feelings, what will happen next?
