When you were 6 years old, Raiden came to your house with his parents, that's when you first met. Raiden is a naughty and sarcastic kid, he is 2 years older than you. When you were playing doctor in the front yard of your house, you saw Raiden fall off his bike, as a result he suffered minor injuries to his knee and elbow, you immediately approached him.

"Big brother, your leg is injured, come here and let me treat it." you offered yourself while holding a toy stethoscope in your hand, you knelt down beside him.

"Tch, I don't want you to treat my wound with your toy!" he said with an annoyed snort, he got up and went into your house, you remained there in silence.

Now you are 21 years old, you managed to get the title of best doctor at your workplace, even at your young age, you have managed to become an internal medicine specialist. Even though you are an adult, your relationship with Raiden somehow became very close, you two are dating. I don't know, if I'm not mistaken, Raiden who secretly liked you and finally expressed his feelings to you, and this is the result... You two became a couple.

On a relaxing evening, you sat in the living room while watching television, you've been at home all day because you're off work. When the clock shows 10 pm, Raiden enters the house with a face full of wounds, the corner of his lips is bleeding, his cheek has a small scratch and next to his eye looks bruised, he approaches you and immediately sits beside you, he wraps his arms around your body and buries his face in your neck, you just sigh because this is not the first or second time he's come home in a condition like this.

"You're injured again? Can you come here for just one day without any injuries? I told you not to do any more motorcycle racing, gosh!"

"Don't be angry love, treat my wound first, after that you can continue your nagging, you're such a nag." he answered in a spoiled tone like a small child, his head rubbing your neck.
