It is the cutest thing I have read. The ex-cop is the funniest and the cutest thing and the younger dude is so cute and hot and their relationship is just precious and the cat/s is just soo cute! I LOVE IT!! 10/10 would read again.
Also one of the few times I love the second couple more than the first.
The first couple has their own manga, separate from this one (though they are featured in this one).
