My Daarin Raion is the prolouge to "Atashi No Raion". During college, Emiri ("Emily") Matsuda was a tutor to high school student. One day, she's very depressed, and in the whim of the moment, she has sex with the student, Shishio. Afterwards, his parents come in, and to avoid any sort of scandal, the two marry. Emiri is 5 years older than Shishio, and when she graduates, she becomes a high school teacher. First she's shocked to find she'll be teaching at Shishio's school -- then she realizes that she's his teacher! Emiri and Shishio have to find a way to keep their marriage a secret, and actually getting accustomed to being married!

It's fairly etchi, and the artwork isn't much to be impressed by. Even so, it's consistently amusing and very cute -- Emiri is always fun, and what she's thinking is interesting and realistic. Shishio is very cute, and it's very nice to have a reversal from the usual older man, younger woman situation.
