Ore no Kanojo to Osananajimi ga Shuraba Sugiru

Eita Kidou intends to concentrate on his studies and avoid romance, until Masuzu Natsukawa proposes a fake relationship to deter her persistent admirers. Holding an embarrassing secret from his past, she leaves him little choice but to play the boyfriend he never wanted to become.

His childhood friend Chiwa is far from pleased. When Himeka and Ai enter the picture with their own claims on Eita's attention, a plan meant to prevent romantic trouble becomes its source. Maintaining the performance grows difficult as genuine feelings emerge beneath the teasing, jealousy, and competing versions of his past.
