Reitia sometimes has things which she cannot do for Angelica as a (single) mom. I guess she be glad to see Galtor to help out as a dad/husband.
This slice of family life is kinda warm.
It would be classic and a bit stormy, if Shiori found these two. (I hope not)
By the way, it's rather contradictory, since Akari's goal is Tenjin Minami and she knows Yakuin wants to be the guy for Shiori, but she still made moves towards Jirou (just like the invitation to the beach stall)...
