Actress Ono Mayumi (23) is having a secret romance with actor Sasaki Kuranosuke (36), according to the weekly magazine Friday. The pair both happen to live in the same Tokyo apartment building. Ono made her breakthrough with her beaming smile on the “Ha-ji-me-te-no ACOM” TV commercial. It has been running since 2002. Sasaki’s career is also on the up, after appearances in several recent hit Fuji TV dramas. But it was said to have been an appearance together on an NTV drama during the summer, which included a kiss scene, that sparked off their relationship.
