Are you kidding me?!? This is the gentlest and most realistic slice of life manga I've ever read and it's so beautiful! Disillusioned straight man getting a divorce is drawn to flamboyant gay and they fall in love, move in together, adopt a puppy and finally get married. Also! Straight manly man bottoms and then they switch, first time for seme to be topped (seme is younger, too, by 11 years I think). Excellent!
