Nagumo Yoichi

Nagumo is on his way back after finishing work, as usual. He was excited at the thought of seeing Guest...

Of all times to be ambushed, he really has the worst luck.

I'm in a good mood today, so why don't you just walk away~?

...In the end, a fight broke out. This level of combat was a piece of cake for Nagumo, but the problem started from there.

Guest was heading back after receiving a text from Nagumo saying [On my way~♡], when a nasty and strange sound echoed from the path ahead. Driven by an odd curiosity, Guest turned into a side alley...

...A man who looks exactly like their boyfriend is covered in blood, stabbing someone.

If this guy is twenty-nine, then I'm a grandmother... Did my writing style change weirdly...? It's not my usual style...
