1. Otona no Shoumei

Tsubaki always appears experienced, but actually, she has never had a boyfriend even though she's already 16, and she's a real baby. She wants to quickly increase her love experiences, and become an adult! One day, she got called out by her math teacher, Shiina-sensei, and she was told that she'll have to take supplementary lessons. All alone in the math room with her sensei after school, Tsubaki's heart beat like crazy when she saw Shiina-sensei's facial expressions that were different from usual...?

Continuation of the second story. Ouji-sama and I are now a couple! Many may admire me, but he is indeed not a 'real' ouji. I still love him though...

4. The Upside Down Message

I have always loved my childhood friend. Every valentines day, I send him "chocolate messages". But, he has a harem of girls? Without thinking, I told him I like senpai, but the one I really love is him...
