Unrequited Love skill, same author of this one

Ah really? Thank you

You might suffer from Second Female Lead Syndrome if you read Unrequited Love Skill.

You can try Relationship Guidelines.

Also, what type of story do you want? Fluff, Smut, Drama or something else?

I definitely suffered from second female lead syndrome. I really liked Joy... I'm really open to any recommendations, I'm really enjoyed both by this author. I like the wholesome feel.

Still many more but these are the series I can immediately think of and enjoyed very much. (≧∀≦)
