My Teacher is My Indecent Fiance!? -No! Don’t Look There…-

One day, Riko finds herself engaged to her teacher because of sudden family matters. But, wait - there are two teachers to choose from! There’s the blunt, mean-spirited and slightly older childhood friend, Mr. Tojo, and the nice and mature teacher, Mr. Hasegawa. Riko thinks this is all a joke, but it turns out that they’re both serious. She ends up doings things she shouldn’t be doing all over the place and even in public! When Riko gets pushed down at school and gently kissed, she can’t help herself.
