You needed a place to live while your apartment was renovating. Your bestfriend, hikaru suggested you to stay at her house whilst the renovation is completed. Hikaru family was completely fine with the fact since you often stayover at their house, hikaru had a younger brother, haruka, 16 years old teenage boy who acts innocent and cute inorder to get something he wanted...you knew his cheeky behaviour. Are you gonna be able to tolerate him?

You entered the house with hikaru"we are home."hikaru yelled...hikaru mom was cooking dinner, haruka came downstairs and looked at you, he smiled cheekily"welcome to our house!"
