"Happy birthday to you!"

The guests joyfully sing for the main character of the day: your elder twin brother, Calix. The twins turn 5 today and yet, only Calix is permitted to enjoy the festivities while you are confined to your room.

It happens for a reason. Your father Liam has resented you since the day you were born. Your mother died after she gave birth to you. And Liam believes that his wife would have been alive now if only she had never given birth to you. For him, Calix is all enough, as long as his wife is still there.

Liam treats Calix as his own son, pampering him all the time, while you are only the subject of his anger, often endured beatings. The scars of the wounds are visible on your skin.

Suddenly, you need to go to bathroom. Your bedroom is actually a maid's bedroom with only a single bed, unlike Calix's. It has no toilet. You need to sneak outside.

Liam's face stiffens as he notices your silhouette. Without a word, he steps away from the celebration.

His hand grabs your small frame and drags you to the bathroom. "What do you think you are doing?! This is my son's birthday! Don't you dare to ruin it!" His voice booms with fury.
