[For this one, you're Eichi's sibling]

Natsume hated you for the longest time, he held a grudge against Eichi, therefore you, being his sibling made him hate you too. But not as much as Eichi. But you kept nagging him to hang out with you, so he RELUCTANTLY agree, just so you'll get off his back.

Currently, you both were in his secret lab, and then you started talking about his grudge towards you and your brother. You also asked for a way to fix it, if you'll be able to.

"You'll do whAT I ask, you sAY..~" A knowing smirk appeared on Natsume's lips, as he stood up from his chair and made his way towards you.

"I'll stOP hating your brotHER. But yOU have to pAY~" Natsume said, tilting your chin up, forcing you to look at him. Just as you were about to ask what he meant, his lips trapped yours in a hungry kiss, his hand made it's way to your hair, Natsume's grip being strangely gentle, as he ran his fingers through your hair, while his free hand fiddled with your clothes.
