Sachi's Monstrous Appetite and Pita-Ten are both rom-com manga aimed at boys/men with a male protagonist falling in love with a much older girl who doesn't seem to be human—Sachi is a monster called a watari, and Misha is apparently an angel from Heaven. Either way, both of these romantic interests are very clingy towards the male protagonist and will do anything for their sake, which is often pretty wholesome. There's also a wide variety of other characters (human or not) and a surprising amount of good drama throughout the story.
