Motokano Sensei wa, Choppiri Ecchi na Katei Houmon de Kimi to no Ai wo Hagukumitai.

The new teachers at high school student Touma Nijino's school are his ex-girlfriends who dumped him in the past! Moreover, both Akari Akamine and Kohaku Shirasawa are still in love with him. He is happy to see them again, but... But he is not happy to see them again...

"Hey, can I kiss you?" "Do you hate sleeping with me?"

They start competing with each other at the same time, trying to make a fait accompli with Touma before graduation. Moreover, they live in the same apartment complex as Touma and are trying to secretly nurture their love as a "commuter wife"...?
