More chess with a cute tsundere

"Alright, this time I'm gonna win," Nina declared as she opened with knight f3.

I simply nodded and moved my pawn to d5. Nina mirrored me by moving her pawn to d4, and I decided to mirror her by moving my knight to f6. Then Nina moved her bishop to f4, prompting me to move my pawn to c5. After Nina moved her pawn to e3 though, I began applauding her. "Well done. I'm surprised you know of the London system," I said as I moved my knight to c6.

"The London what?" Nina asked as she moved her pawn to c3.

"The formation you're doing. It's called a London system," I explained as I moved my queen to b6.

"Uh, is it good?" Nina nervously asked as she moved her queen to b3.

"It's one of the best openings out there," I stated as I moved my pawn to c4.

"Oh, then I'm gonna win then," Nina smiled as she moved her queen to a3, unknowingly blundering away the game.

"Well, she is still learning," I thought as I moved my pawn to e5.

"HAH! Now I can finally put you in checkmate!" Nina declared as she captured the bishop at f8 with her queen.

"Sorry to say, but that's just a normal check, and your queen's gone," I stated as I captured said queen with my rook.

Nina's confidence immediately deflated as she began to tear up. "Oh come on! Go easy on me!" she pouted as she captured the pawn at e5 with her d-pawn.

"Sorry, but failure is the greatest teacher in cases like this," I sighed as I captured the pawn at b2 with my queen.

At this point, Nina had pretty much forgone strategy and moved her knight to d2, allowing me to capture the rook at a1 with my queen. Nina desperately moved her knight back to b1, but I simply swept it up with my queen, prompting Nina to move her king to d2.

"If you're trying to attack my queen with your king, it won't work. Check," I stated as I moved my knight to e4, forcing Nina's king to e2.

"This isn't fun," Nina pouted as I captured the pawn at c3 with my knight, forcing her king to d2.

"Perhaps I went a bit overboard. Sorry, I only remember how to play competitively," I nervously smiled as I moved my queen to b2.

"Well ease up, or I'll never play chess with you again," Nina huffed as she moved her king to e1.

"Alright. Checkmate. I'll be sure to praise you and go easy on you from now on," I smiled as I moved my queen to c1 and began patting Nina's head.

"You better," Nina blushed.
