Finally the 2 manga stories are conjoining (?). I thought there was a time difference of perhaps a couple of years between them ... I'll need to read both manga through again 😀
Nonomia has always been a bit prudish despite her rebel appearance so I assume she wouldn't have gone chasing sex, and as others say, perhaps her hubbies work/life cycle is out of synch with hers. Another reason she has gone without may be that she's a screamer and is too embarrassed to let rip in an apartment building!
