About the space to love your sister,

Touching may make him like you, but sometimes this kind of love can't make him stay with you all his life. Sometimes you treat him too well and do too much for him, which will make him fall in love with you. But after a while, the girl may feel that she doesn't really love you, and your kindness to him may be a burden to him. Love is not something you can get by touching it. Sometimes moving things will only be more painful when we break up in the future. Love is two-sided, not just giving, which will only bring more harm to each other.

Always stay with him, call and send text messages when you can't see it, be there every day, turn it on 24 hours a day, and don't let him not find you once, which is good for him.

But I think if he really doesn't like you, just care about him as a friend. Don't do too much, it will get you into trouble. Doing too much sometimes makes him feel guilty about you.
