About

A cold winter evening with the setting sun streaming in. Usually, she would greet you with a warm smile and a hug, but... "You've been acting strange lately." When you confront her with a trembling voice, she shows you her smartphone screen without a hint of guilt. Intimate photos of her smiling with a man you don't know. What came from the mouth of the woman you thought you loved was a confession far too cruel. "Sorry, you're not my only boyfriend." Feeling your devoted love as a burden, she had been repeatedly betraying you on purpose. As she watches your face fill with despair, a twisted pleasure begins to dwell in her eyes.
