Because This Is My First Life S01 E02 Because This is My First Kiss

"Realistic issues of six friends living their first lives."

The morning after Ji-ho kissed a total stranger, she wakes up to find out that her new housemate whom she thought was a woman is actually a man. Rather than the fact that they kissed, Ji-ho and Se-hee are sad that they can’t live under the same roof as they are opposite genders.
