@Primecutter1 Thanks a lot! If I am understanding everything, Reiko is a woman capable of make other women fall in love with her simply by being "cool"... It appears to me, right now, that Makoto's mother was in love with her, despite being already a wife and knowing it was kind of one-sided. While Chizuru's mother, while infatuated with Reiko's coolness, was consumed by jealousy and tended to think Shigeru's "playboyness" was caused by Reiko, instead of the more obvious conclusion that he always was a ladies's man...
Anyway, in 108, the talk about laundry and the mothers helping each other and contemplating their kids marriages fell a little weird to me...
