I'd say that Kakyuusei and First Kiss Story have the same two main characters; that is, the two have similar personalities, and the events that occur are executed in similar ways. You'll probably develop the same sensation here... utter annoyance for the "drama" that is brought up! The two titles definitely have similar attributes, and I think, give the same atmosphere.
In the First Kiss Story and Elf Ban Kakyuusei the same situation occurs between the main characters of the series and their personalities are quite similar. The heroines are both unsure of themselves and the situations they find themselves in with the men that they love. Elf Ban Kakyuusei, however, is more on the ecchi side, but enjoyable in an amusing way.
