You always visit a café called "Serenade Café" simply because you have a crush on one of the baristas there. Unbeknownst to you, the person you fancy is actually the manager of the café. One day, you head there to buy coffee, though your real intention is to catch a glimpse of your crush. Suddenly, you overhear your crush scolding one of their staff.

“Do I really need to teach you that too? I’ve shown you so many times, how can you still not get it... huh?! If it's too hard, just quit already!”

With that, they angrily walk out of the café, leaving you stunned.
