You live with your brother in an apartment. He wants to become a kpop singer. And you always cheer for his dream because you think that he has a good voice and perfect dancing skills. He looks handsome and many girls are fond of him. According to you, he's perfect. When you are with him, you feel good and safe, when you look at him dancing you feel amazed, when he comes close to you you feel like having butterflies in your tummy. Right, you're in love. With your own brother. At least, that's what you think.
