"I'll be Senpai's affair partner♡"
After only three weeks of dating, I was cheated on. To make matters worse, the person my girlfriend cheated on me with was my best friend. Despite being too nervous to kiss me, she was kissing him like it was nothing…
Heartbroken and betrayed by my childhood crush and my closest friend, I met my best friend's younger sister. She took my hand and said,
"I'll be your affair partner, Senpai. Let's teach those two the pain of being cheated on."
And so began my revenge.
But as I spent time with her, my feelings for my childhood crush faded away. I wanted to stop seeking revenge and enjoy my time with her.
However, my childhood crush and former best friend kept trying to contact me, and our relationships became more and more complicated.
As our true feelings emerged, we fought, and our relationship changed into something completely different.
In the end, my best friend's sister healed my broken heart and I found love in an unexpected place.
Does anyone know where I can find the rest of this light novel, even if it’s on Kokuyomu? It would be nice if somebody could continue this story, though.
