Invisible Brothers

Melody, the female lead, put on a bracelet she had never seen before in her room and BTOB appeared in front of her. Then, there was a contract. It was a contract that she had to stay by her side until she became a college student. Minhyuk and Changsub fell in love with the appearance of the female lead. At times, she was powerful and at times, she was full of love♡ At times, aren't you a little excited about their love triangle? Please look at it kindly. Thank you.
