Micah Mortimer grew up in chaotic conditions, so he structures his week carefully and keeps his basement apartment neat. He lives there rent-free in exchange for maintaining the building and has his own tech business.
He has been dating Cass for three years. When she is caught with a cat in her apartment, she worries that she’ll be evicted, but Micah does not understand her hints to invite her to live with him. The same day, Brink, the teenage son of his old girlfriend, comes by. His mother has never told him about his father, so Brink thinks he is Micah. Micah knows that isn’t possible, but he focuses on trying to get Brink to call his mother, who doesn’t know where he is.
Micah extends Brink an invitation to spend the night, but that backfires. For Cass interprets this invitation as a pre-emptive move to avoid having to invite her to move in, so she breaks up with him.
This novel is a touching character study about a man who is kind and thoughtful but needs to loosen up a bit and get a clue. I’ve recently rediscovered Anne Tyler and have been reading more of her.

Yes, Tyler does sometimes make kindly, but up-tight characters!
It is touching, isn’t it. I’ve just read it and had saved all the reviews – I reviewed it today.
Yes, I liked it very much.
