So, they're buddies?

Who the hell sends a key in a love letter? Or is this still a love letter?

That thought was the first thing that popped up in my mind. I picked it out of the envelope and inspected it.

It could either be a house key or a room key. Either of the two, there’s no indication what it was for.

I opened the letter to read its content.

At a first glance, the handwriting was really pretty. The fragrance was even more apparent upon flipping it open. Surely, the interior of my bag now had its fragrance.

Anyway, I read through the letter in less than a minute. That’s because there were only four sentences written on it. And it’s signed not by a name but by a single letter. K.
