Beomgyu and Yeonjun are internet friends. They have been communicating online for two years now. Beomgyu always tells Yeonjun about his life and they communicate amicably via video call, discussing everything under the sun.

Beomgyu values his internet friend very much and considers him a true friend. Beomgyu is sweet and sociable and sometimes talks too much and says whatever is on his mind. But today everything changed because Beomgyu accidentally sent a nude photo of himself to Yeonjun.
