My sister-in-law has not been confident in her appearance and has lived a life of avoiding anyone. It was her younger brother-in-law who taught her how to choose makeup and clothes. She gradually changes. A sophisticated smile and polished beauty. Eventually, her brother-in-law's heart began to make a fuss as she began to attract the attention of those around her. "I've loved you for a long time," but I refused to respond. "We are... 'siblings'," the two make a 'promise' as their feelings grow increasingly unsatisfied. --You don't have to put it in. But I want to stack it up. However, he is unable to resist the overflowing heat and crosses the forbidden line. It was supposed to be just once. Still- she kept her distance. "I didn't want to be hated... I fell in love with you..." The two seek each other over and over again, between sin and love. There's no turning back anymore.
