The couples-only screening event for the movie "Hidamari no Kanojo" was held on 7 October which was attended by the lead actors Matsumoto Jun and Ueno Juri as well as the director Miki Takahiro. The movie will be shown in cinemas from 12 October. During the event, the audience was asked for stories about secrets they kept from their partners and there was this particular story of someone writing messages of love on the back of a stamp that was affixed on the postcard sent to that person's loved one which made Matsumoto very impressed. When asked about their own secrets, Matsumoto jokingly revealed that he had been told that he's an alien when he was in Arizona for a trip about 5 years ago.
