Both of them are co-stars in Ultraman Geed in which aside from being Ultraman Geed's suit actor, Iwata also played Zena, an Alien Shadow and an A.I.B. (Alien Investigation Bureau) agent. Hasegawa on the other hand, played Zena's junior agent, Moa Aizaki.
From all of us here, congratulations to the happy couple!
