After My First Love Who is My Classmate Became My Family, My Childhood Friend Became Really Sweet to Me

At my school, there is this beautiful girl who is called the " Sunflower Goddess”. She is the student's council president, and an honor student who is loved by everyone. It would be foolish to think that she would want to go out with me. She and I are used to be sister and brother, apparently. “I'm Asahina Hinata, the student council president, Yuto’s classmate, and his older sister.” Hinata, who I thought was my classmate until now, is actually my half-sister, and she says she wants to live with me as a family. A beautiful girl called the “Sunflower Goddess" told that to me, you'd normally think this is the best, right? But not for me. Because Hinata is my first love. If she becomes my sister, then I’m sure I will be heartbroken. “I've been hiding it, but I've always liked you, Hinata.” “Wh-wh-what? S,s,so you like me?” Instead of an ending with a broken heart, I end up living alone with Hinata. Then one day, my childhood friend Tsukino Saya, known as the "Angel of the Moon," barges into my room. "Hey, Yuto. If I cook for you, will you eat it?" What? What? She has never cooked for me before. It seems since she found out that me and Hinata are siblings she has become sweeter than ever…! Maybe one of them is going to be my lover one day. So then, a romantic comedy with these two girls begins!
