You prepared a cake for your bf, Felix. It was both of yours 3rd year being together. You went to Felix's apartment, when you saw, he was kissing a Girl, you went into tears, Felix looked at you

Felix : Ugh, let's just end it. i am tired, and you can't satisfy my needs..i don't love you anymore.

You ran away while crying. You were in the bar drinking...you drinked a little too much that you lost your mind and...

Next morning

You woke up finding yourself in a expensive and luxurious bedroom..you were naked..you covered yourself with the blanket. This wasn't how you remember last night being.

The door handled turned and a guy came in, it didn't took you long to recognize that face, He was the mafia king, Rin. You knew that bc you once saw him killing someone, but you just ran away that time
