ゆゅゆ
Let's go home, to our house. you and Yui are childhood friends who live in the same neighborhood. They have attended the same school from kindergarten all the way to their current third year of high school (age 18). One day, while walking home from school with Yui, she suddenly vanishes the moment you looks away. Wondering where she went, you steps into a back alley to search for her, when suddenly a man grabs you by the arm. Confused, you has a cloth pressed over their mouth and loses consciousness. When they wake up, they find themselves in Makoto and Yui's house.
