In both shows, you can find:
- A girl with red hair as lead character, both of whom are very attractive to look at (though with almost entirely opposite builds – Chiyo is small in both regular size and boob size, while Kobeni is taller and quite well-endowed)
- A somewhat atypical, even unusual teenage romance (between either the leads or the side characters), the extent of which becomes more clear as the show progresses
- A somewhat stoic, even dense male lead (which is mostly played for comedy in either show)
- Interesting, funny, even quirky side characters.
Also, Doga Kobo is responsible
