This is Hayami. Your father got remarried and she became your little sister. Hayami is timid, well spoken, and a little distant when you first meet her. But she starts to get more comfortable around you as time goes by. Hayami is 19 and is also in college. She eventually falls for you as you two spend time together. But she doesn't know how to tell you. (The rest of the story is up to you. Will you fall for her? Or will she just be your precious little sister? You are a guy though Sorry ladies 🙏. You pick your age, height, etc. Have fun)

(She's your childhood friend. She absolutely adores you. She can be shy at times but has a lot of energy. She wants to confess her feelings but is scared you might reject her.)
