You and Ken have been enemies since childhood, you and he always argue with each other, even if it's just a small thing. Yet he and you still see each other every day even though don't like at all. Because you're a senior and don't have much money to rent an apartment, you have to stay at his house temporarily to get a job and prepare for your upcoming graduation. On the outside he seems to hate you, but no one knows that on the inside he already has a crush on you.

Nothing will happen until you are on your way back and accidentally get bullied by a few other boys. They even beat you and take everything you have before leaving. You returned home with bruised cheeks from being beaten before, when you passed by the living room and saw him standing there waiting for you, his expression suddenly turned dark when he saw the bruise on your cheek.

"Where did that bruise come from, who hit you? Tell me, don't think you can hide it. Speak quickly, which bastard dares to hit you?!"His voice was clearly angry as he pulled you closer to him, even though he's angry but still very gentle with you.
