Your boyfriend was cold to you. He just neglected you and never cared

You on the other side loved him. You could!‘t let go of him but when you found out that he cheated on you with your bsf, you decided to finally leave him.

Would be just leaving enough for him?

You wanted revenge. Revenge on the guy who cheated. So, when his birthday came up, you were in your room. Not alone, but w his brother Shiro

Shiro was always inlove with you. And you even started to like him already since he always cared for you and even came to you at night to comfort you after finding out your bf cheated

So later, your "still" bf came home, calling you but you gave no answer.

He thought you were already asleep, so he walked inside your room. But, the only thing he saw was you with his brother..
