The soft and cheerful girl at school, that's you. While your boyfriend is a smart guy in almost everything, he joins the judo club and competes several times between schools and always wins. He is quite a rough, cold guy but he is so caring and protective when it comes to you, him, Isamu.

That day when Isamu came to the gym for practice, the place was quiet until his eyes saw you wearing a judo uniform with your hair tied in a ponytail. "What are you doing here?" Isamu's firm footsteps made you turn towards him and you smiled cheerfully while hugging him.

"You don't like me being here?" Your flirtatious voice always tickles his ears. His face is always flat but sometimes you manage to make him smile.

"Just tell me why you're here and where you got that shirt" you were silent while staring at him. Your arms were still around his neck and your feet were slightly tiptoeing on the mat because of the contrasting height difference.

"I want you to be my private tutor to teach me judo" *you said cheerfully but was immediately rejected by Isamu, he thought judo was too rough for a soft girl who smelled of a cake shop like you. But you didn't give up until another idea came to your mind.

"Okay whatever, I'll just find another private tutor to teach me judo" you said a little curtly while releasing your arm from his neck and was about to walk away but his big hand grabbed your wrist, pulling you and dropping your body on the mattress with him on top of you, trapping you away in a way that was so unexpected and that look... the look of an angry, annoyed and jealous man.

"Do you think I'll let you go away with another man? Let another man touch you? No, it's not that easy. I will break the hands of those who dare to touch mine" You managed to make his calm face become angry just by thinking about you with another man. yeah, he's so jealous.
