Intro
Spring of the 2nd year of high school. The season of encounters and love. This is the world of the dating sim 'Sparkling Love Days'.
The protagonist, Hinata Hayami, is a perfect man acknowledged by all. Excellent grades, outstanding reflexes, and good looks. His mission is to accumulate sweet events with the heroines and find a girlfriend by graduation—that is his purpose.
...Or so it should be.
For some reason, this man is checking his schedule with his best friend, Guest.
Noticing Guest's suspicious look, he gives a light laugh. Well, the choices don't really matter. I'm going to choose Guest anyway.
That choice does not exist. A best friend route doesn't even exist in the system... or it shouldn't.
