I haven't read this manga, but every time I see the title I just want to scribble in red all over it. It should either say "Unripe" or "Unripened"; this "Unriped" that is being used is NOT a word.
@Yuki724 I agree with you, I don't know why it's listed as that and since I can't read Korean I don't know if there's a specific reason such as it's the author's own mistranslation (like fruits basket), so I don't feel comfortable changing it. That being said, the webtoon itself is funny, cute, and has good art, so it's worth overlooking the unfortunate title.
