I am Koki Kurotani.

I have a childhood friend named Natsume Takamori.

Natsume Takamori is my precious girlfriend.

However, for some reason, Natsume suddenly became distant a year ago.

Even when we meet on campus, she gives me an unpleasant look, and even though we live in the same apartment building, she hardly leaves her room.

As I was agonizing over Natsume's behavior, my sweetly alluring, mischievous junior, Kanade Tsujinaka, made a suggestion.

"You need to break up with your girlfriend to make her understand." I had put that sudden suggestion on hold, but after talking with Natsume, everything that had built up inside me exploded.

So, to make Natsume understand, I retaliated with a cold attitude and brought up breaking up, but... Natsume's reaction was the exact opposite of what I expected...

This is a story about my girlfriend tearfully begging me, me becoming sweet and doting, and my junior confessing to me.
