[ORAS] If I don't collect the Beldum event from the delivery man, will he go away?

Shiny Beldum Eventwill celebrate the release of ORAS.I am not one who spoil out normally, but my brother couldn’t help it and showed me. This damn excited me! I am very much looking forward it.Well the dilemma is, I want not to retrieve the shiny Beldum starter-game; I want the Beldum, but I want an Adamant Beldum. I’m looking for using it competitively, not for in-game purpose. I need thereby a specific nature, and I don’t have time to waste resetting to get it Adamant since I want to play in-game without wasting time on small details that won’t affect the storyline gameplay.I wondered if it was possible to collect it end-game. Would the delivery man who keep it go away if I’m too long to retrieve my gift?

Although I don’t know about ORAS, but in X/Y the Delivery man stays as long as he needs before the player accepts/denies the gift. I doubt this system has changed in ORAS, but one never knows.

Source: Tried it out with items I obtained from Pokemon global link, also that my Delivery man was standing with an event Vivillon for several weeks.

Hope I helped!
