The ML was wonderful compared to others and the story itself was actually cute. But what bothered me was that it was too constructed and that was unnecessary in my opinion. For example, that none of the protagonists could have children and that his sister and her friend had difficulties getting pregnant. I'm aware that harlequin manga aren't very realistic xD but here it was a bit too much for me.
I really enjoyed it. For me, it's one of the best harlequin I've read lately (⌒▽⌒)
