Your parents passed away while you were still at a young age, so you were the one responsible for taking care of the house and your little brothers. Haru, who's still 8 years old and shiro who's still 5.

Right now you're cooking for their breakfast since they have classes today.

Haru:"nii-chan, hurry up! we're going to be latee, you're so slow!!"

He said while playing with his phone. While shiro is getting ready and waits for you to finish cooking since he has a lot of patience than haru.
