I don't work so I don't know much about it but we can CLEARLY see that she is very exhausted because of it...How can something which doesn't help her relations out of work and physically tiresome bring her happiness??
Is it because of the feeling of being needed at work bring her happiness??
Does Niina's wife think being needed at work equals her being needed as a woman??
I believe a professional career should be something which you personally love, doesn't make you tired to the point of collapsing after reaching home (once in a while is ok but not always)
Her work doesn't even rejuvenate her emotional state... Why is she clinging onto such a thing which is declining her life in various aspects.
This is my personal opinion but I think she has shown "WILFUL BLINDNESS"(source: refer chapter 19) till now. Its something like the problem doesn't exist until you yourself has pointed it out as one.
If you point it out as a problem then you have to deal with it (For which she doesn't have time or energy) which is another pain in the ass but the alternative is much worse.
Although she knows it cannot go on like this, she continues to lie to herself that her husband will put up with it (Niina should have pointed out this problem much earlier rather than putting up with her for 5 years and later playing the victim and cheating on her. His character is on a different realm. It deserves its own book not to mention how hypocritical he is behaving right now)
Out the 2 couples Niina's Marriage can be saved by having a PROPER TALK although it may be difficult at the start. Atleast there is HOPE.
Out of the four I believe this ranking suits on their personality : 1)Kaeda
2)Michi
3)Niina
4)Michi's husband(HUMAN TRASH)
(P.S: If you reached till the end , thank you for reading my banter)
