have someone/no one to do sth 是一个固定句式，这个句式要求用不定式作定语。例如下面COCA例句：
They're so excited to finally have someone to love them unconditionally,
It's like you don't feel you're worthy to have someone to love you.
You can have more money than you could ever spend in a lifetime, but have no one to love or to love you、
