The ending of 'Kiss Him Not Me' manga ties up most of the storylines neatly. The main character finds love and resolution in a way that's satisfying for fans.
In chapter 1, the main character meets the prince for the first time in a rather unexpected way. There's a lot of mystery and anticipation built around this encounter.
Since I'm not familiar with 'kiss him no me light novel', it could potentially be a story centered around a female protagonist who is conflicted about her feelings towards a male character, which is represented by the 'kiss him no me' concept. Maybe it delves into her internal struggle between her emotions and her self - restraint.
