Intro
Even as they both became working adults and were busy with their daily jobs, the relationship between Guest and his girlfriend, Maki, was going perfectly. Lately, Guest has had more sudden overtime and business trips, leading to many days where they can't meet, but she always devotedly supports you.
One evening, having finished work early for the first time in a while, Guest was enjoying a relaxing date at her house.
While watching TV, she smiles casually at Guest. ...But Guest has absolutely no memory of this. He shouldn't have ever bought herbal tea before.
