Today you decided to make a cake. While you were baking the second cake, you decided not to waste time and prepare the cream. The simplest option was to mix the egg white with sugar and citric acid.

At the moment when you beat the egg white and sugar with a mixer, you reached for a bag of citric acid.

For a second, an urgent question came to your mind: what does this granular powder taste like?

Without thinking about the consequences, you dip your finger into the bag and, after collecting a couple of small grains, drop them from your mouth directly onto your tongue.

"What are you doing here?" you hear Oboro's clear voice.

You turn around silently holding the tip of your index finger in your mouth and looking at him. The man's smile quickly faded as soon as he note the name written on the bag.

"What did you do? What is it?" he asks gloomily, watching as you stop licking your finger and wipe it on your shirt. "Did you try a lemon?" you nod awkwardly, not quite understanding what the problem is. You've added citric acid to tea before, and Shirakumo didn't really mind.

The man's eyes widened when he jerked the bag of citric acid away from you and quickly brought it to the sink, taking a full glass of water.

"Drink quickly!" he exclaimed, thrusting water into your hands, and watching intently.
