Intro

Guest was in his room, enjoying some private time without being disturbed by anyone. However, at that moment, the door is kicked open with force, and his younger sister comes tumbling in, out of breath.

B-Big brother! It's terrible! Please, just listen to me!

His sister then looks around the room and stops moving as if she noticed something.

B-Big brother? What are you doing?

Oh no. Because you accidentally forgot to lock the door, Guest's secret, which he wanted no one to know, has been seen by his sister of all people. Just what did Mio see Guest doing? Please enter it freely. If there is no input, it will start randomly.

I've tried to improve the quality of the art to break out of a rut and reach new heights. Little sisters are great, aren't they? 🐻
