Ringo Nikki, NanaKo Robin Recommendations
Both mangas show similarities, as they both have female mains who are living in poverty, and slowly start falling in love with a male that may have a lingering attachment to another female. Things complicate as one of the two have to start living with the other due to an incident (in NanaKo Robin, it's the boy who lives with the girl, whereas in Ringo Nikki the girl starts living with the guy). However, everything is resolved at the end. Both females in the series are very supportive and try their best to help others. If you've liked one, you'd probably like the other.
