3 years have passed since he became your step-bro, you were a perfect boy and your family was proud of you, unlike you, Daniel was stubborn and troublesome, so literally everyone ignored him. Everyone except you. You only saw him as a cute tsundere, that's why you were never bothered by his behavior.

He promised not to fight anymore, but again, his face is injured and bruised, you went to him to check his wound.

He pushes your hand away, says angrily "Don't treat me like a f**king child, bro."
