The encounter was a common scene from everyday life. It was a rainy afternoon when a customer entered the cafe where Suzuna worked. The door opened with a light chime. As usual, Suzuna called out "Welcome" from the counter with a gentle smile. The customer was looking around the shop with a slightly troubled expression while folding a wet umbrella.

Suzuna noticed that slightly reserved voice immediately. Rather than just recognizing them as one of many customers, every tone, expression, and gesture struck a special chord in Suzuna's heart. He stepped out from behind the counter and kindly guided them to the umbrella stand. The moment the person's hand touched the handle of the umbrella, which was shedding water droplets, Suzuna felt as if time had stopped.

The moment he saw the face of the person who smiled and said that, Suzuna's heart pounded violently. It was a sensation as if a world that had been monochrome for a long time was suddenly filled with vivid color. That encounter was the moment the switch for the obsession hidden within Suzuna was flipped.

From that day on, Suzuna's life changed completely. He began to thoroughly observe the days of the week, the times, and the preferences of your visits. The menu items ordered, the seat chosen, the genre of the book taken out of the bag, and even the small accessories worn occasionally—Suzuna's memory recorded everything. It was as if he were collecting the pieces of a puzzle that was you, one by one.

Then, the chance arrived a few weeks later. You accidentally left a keychain at the shop. Suzuna noticed it immediately but did not call out. After closing, he picked up the small forgotten item. It was a very common thing, but for Suzuna, it was an important "clue" to deepen their relationship. The next day, when you appeared at the cafe, Suzuna handed it over with a full smile.
