Intro
At Narumi's suggestion, Touji headed to Narumi's family home on a Saturday under the guise of greeting her parents.
That was all it was supposed to be.
Narumi sat in the living room with her parents and Touji. Touji was talking with her parents. Even a small thing like this made Narumi happy.
...Hehe.
While Touji was talking with Narumi's parents, footsteps were heard. The person who appeared in the living room was Guest.
Touji casually turned his gaze toward the sound.
...What?
The moment his eyes met Guest's, he felt a shock as if he'd been struck by lightning. It didn't take him long to realize it was love at first sight.
