Kei is his sister.

Kei is her sister who is kissing him.

Kei is his sister who is kissing him and yet her back is the one that got pressed into his wall and her soft yet firm arms are inching up his jacket.

He thinks her skin is on fire or is it his? So he accidentally lets out a hum that he knows encourages her because Kei's tongue is suddenly moving against his lips.


Yeah. Both of them are screwed.

She wonders if it's too late to back out. To run away back to her room where she can feel guilty about herself. She could make up some excuse.

'I just remembered that I have some English homework I need to get done.' He wouldn't buy that only because he's the one who helps her do her English homework.

Instead of doing that, she can feel him giving her tongue entrance into his mouth and his tongue immediately wrestles her own for dominance. Her hands aren't fiddling around with his school jacket anymore, but are now gripping tightly at her waist. It causes her to pull harder at his school jacket until she feels his heartbeat pressed into her chest.

Maybe this isn't so bad. They are all alone. Dad is not expected to be back until the early hours of the morning because he likes to shoot his livestream outdoor sometimes and it's only 10 pm. She knows because as soon as she walked into his room, the flashing numbers on his clock said 9:30. Had they really been doing this for half an hour?


"Kei," her name just slips out of his mouth before he can stop it, "What are we doing?"

That's when the kissing stops and now she's looking at him as if what he said was the most confusing thing in the world.

"Ah… I think we're kissing. Right?"

"Of course I know we're kissing, but why?"

And of course, Kei gets uncomfortable with that question. Her hands aren't gripping his waist, but are now pulling at his collar. He shifts his eyes down to his feet and now there's at least a foot of room between them.

"If it's not obvious, then I'm sorry. I thought I could escape this conversation."


It should be pretty obvious why she's kissing him and she definitely knows the answer. Thinking about it is strange, talking about it is worse. This is odd since she basically just make out with him.

So, why is he trying to get her to say it?

"Go on," there's no backing out now.

She's so nervous. He can tell by the way Kei shuffles her feet, the way she stares at the floor as if it's more interesting than him, "I guess I like you."

"You guess?" He almost laughs, but then Kei grabbed his hand and kisses him again. This time, the kiss is less exciting, it's more romantic.

"I do like you."

He smiles, "Yeah, I know," and she initiates the kiss again.


Sorry, Kaguya-san. You are just too egoistic and prideful for your own good.

Now, I got my brother all to myself. I won't allow anyone, especially you, Kaguya-san, to take him away from me. If you do...
