Egekai no Prince

Alex Stefano, the second crown prince of the Kingdom of Hellenica, is concerned about his daughter, Zoe, who still can't talk. He sends for a speech therapist from New York, but he doesn't expect the therapist, Dorothy, to be such a beautiful young woman! Dorothy befriends Zoe in no time and Zoe's treatment progresses smoothly, but Dorothy has a secret... Dorothy had a son who died when he was the same age as Zoe, and the more time Dorothy spends with Alex and Zoe, the harder it is for her to bear the pain. (Source: Renta!)
