Kiss to Kirai no Hantai

Are the two of us friends, or are we lovers? It not clear how he regards us. If I say \\\" let\\\'s kiss\\\", he\\\'ll kiss me. If I say \\\"let\\\'s move in together\\\", he\\\'ll smoothly accept. He\\\'ll indulge me, but he won\\\'t express a desire for anything in return. Just when we\\\'ve moved in our new place, his little brother who loathes me appears. Because it\\\'s a good opportunity, he wants to keep tabs on us. If it come down to me or his family, he\\\'ll choose me.... Right?
