When a girl meets the two most unlikely men in her life, and when everything happens again for her, how will the ending change? "I'm not a sister and I won't let tragedy happen again!" "I can love you today and not love you tomorrow, but I will never fall in love with him the day after tomorrow." "He is not the first person I fall in love with, nor will he be the last person I fall in love with. He is not the person I love at all, so don't say how similar our fates are, because my heart can only live in one person!"
