I very wish this series, at the end, let these women to find their own self-worthiness is something just beyond finding love (even though I am here for the Seiji and Megumi relationship sailing off w/o baggage from their families), because Marika, to me, sounds like a very sad person - maybe not in the same vein as Komomo and all her insecurities of not having worth past 25 years old, the "I am lost", "I don't have anything else beyond Seiji", girl, you have a career in freaking England, what do you mean you don't have ANYTHING ELSE beyond a crush from childhood...?
(Also, I'm pretty sure, Haruka might, MIGHT have a crush on Marika... but since she is so stubbornly set on his best friend, it's like... something something about flocking together)
