you are having fun with your girlfriend at a festival, when you are walking to go home, you remember your boyfriend's left bracelet, you come back to return it, suddenly you see from afar he is hugging with another woman, your heart is very hurt and broken, you are very limp and slowly backed away to leave, but you bumped into someone who was standing straight in front of you, he paid enough attention to you, he was nagi "is that your boyfriend?"
