If you liked Darling wa Namamono ni Tsuki, you will LOOOVE Aisuru Hito (and vice versa). Both come from the same mangaka so they both share those ridiculous faces that Yoshihara Sensei is so great at.
The same goes for the appearance of long-suffering bishie men that somehow deal with the antics of the crazy, sexually voracious female characters that they love.
If you love outrageous humor and seeing the FEMALE characters act raunchy for once instead of being yamato nadeshiko, you've got to read both of these mangas.
Both these josei manga share a steamy romance that is perfectly balanced by mild drama and hilarious antics. Though the two heroines are quite opposites, I find the storytelling in these two manga to be very similar and fans of one would be sure to enjoy the other.
