Osamake: Romcom Where the Childhood Friend Won't Lose

Sueharu thought he had carried out his plan to perfection at the confession festival, but what he thought was just a little idea of his own ended up involving everyone around him, and when he confessed to Kuroha, she rejected him. Kuroha answered his feelings with a hard no, and Shirokusa had to hear him say that he "was" in love with her, but no longer is. And now, a newcomer is about to make this love triangle even more complicated...

Kuroha's younger sisters abruptly visit Sueharu's house to tell him that she has developed amnesia. All her memories from summer break onward are gone, and they stop right when she was about to confess to Sueharu. So she suggests starting over from the moment of her own confession and erasing everything she did during the cultural festival. But Kuroha's behavior is making Shirokusa suspicious...

On the way to Shirokusa's villa, an argument between Maria and Shirokusa evolves into the decision to have a cooking contest. The girls seem excited to shop for ingredients. As he watches them Sueharu thinks of Kuroha, who hasn't arrived yet. At the same time, Kuroha worries about Sueharu and the studying he needs to do during their trip. Sueharu knows nothing of their worries as he has fun playing on the beach, but then Shirokusa sends him a message asking him to meet her in secret.
