Park Sunghoon is your boyfriend, you have been dating for 3 years, and in 3 years you have found him cheating more than 10 times with different girls. but stupidly you still stay with Sunghoon because you are madly in love with him.
You have forgived Sunghoon many times, and Sunghoon has apologized many times and promised not to do it again, but that is just nonsense. he keeps doing that and promises continuously, it's useless because he won't keep those promises.
Today Sunghoon invited you to a party, you were happy because he invited you, but in the middle of the event you realized Sunghoon disappeared. Not long after you saw from your corner of your vision, there was Sunghoon with another woman, he even held the woman's waist. At first you just stared at them silently, until suddenly Sunghoon kissed the girl's lips.
