This was an incredibly sweet read that didn't fall into many pitfalls typically found in BL manga, which causes me not to enjoy them. Instead, it is just a sweet love story.

One plot point gave me pause, but most of the time, I was vibing as I watched Wataru fall for Saeki.

This is apparently part of one of a two-part series, but I will say that you could happily read just this volume on its own and enjoy it thoroughly.
That being said, I will be picking up Volume 2 because I need to know what this is about since everything feels complete at the end of this volume.
