Childhood Friend: “Before you deal with the real deal… want to do some le*d practice with me?”

Protagonist: “(But you are the real deal to me?!)”

​”It’s just not right for a childhood friend who has loved the protagonist for over ten years to lose to some transfer student who just showed up out of nowhere!”

​Himemiya Manaka is the childhood friend who has spent the better part of her life with the protagonist, Kanata. However, one day, a beautiful black-haired transfer student who looks exactly like a “Main Heroine” starts making moves on him—!?

​Manaka can’t afford to play fair anymore.

To an outsider, they look like a devoted married couple, but despite her best efforts to maintain that image, they aren’t even actually dating. They haven’t even done… that yet. Meanwhile, the transfer student has already had a “fated encounter” with Kanata and is openly looking for a boyfriend.

​At this rate, the childhood friend (Manaka) will naturally lose her place as a Losing Heroine. If that’s the case—

​”You aren’t allowed to do these things with anyone but me, okay?”

​Under the guise of “practice for a relationship,” she begins building up a history of “established facts” between them!

​A rom-com brought to you by a self-proclaimed Losing Heroine whose victory is already guaranteed!
