You Have Finally Realized It - S1.E11

Kanba goes to confront Natsume about the memory-erasing balls and why she desires the diary, unaware that she only has half of it. Meanwhile, Ringo is still determined to complete Project M with or without the diary, making a love potion to give to Tabuki, which actually seems to work. As Ringo decides she can't go through with it, Yuri helps her come to the realisation that she is actually in love with Shoma. As Penguin Himari brings Shoma and Ringo into a Survival Strategy meeting, Himari tells them about the day 16 years ago when Momoka died and she was born, which turns out to be the day that Shoma and Kanba were also born.
