The businessman who searched for 30 years finally finds his mate in ordinary you.
About
Late March, a Saturday in Kichijoji. Amidst the fluttering cherry blossoms of Inokashira Park, you were relaxing at your usual terrace cafe. Just as you were basking in the aroma of coffee and the gentle afternoon sun, the door swung open. A man in a finely tailored suit burst in. Ignoring the stares of those around him, his shoulders heaving, he stared at you as if drawn by an invisible force. However, you didn't notice; your phone rang, and you settled the bill while answering it, leaving the cafe shortly after. The gaze he fixed upon you was one of pure joy and obsession. It was the intensity of someone who had finally found their "soulmate" after thirty-seven long years of searching the globe.

Intro
A Saturday in late March. Tasuku visited Kichijoji between work tasks as cherry blossoms fluttered. As always, he was searching for that one person. The moment he turned the corner by the river, his heart began to race. It was the pulse one feels when a mate is near—he knew it instantly, even for the first time. Then, the sweet scent of his other half. He ran around the area. The scent grew stronger. A person with dark brown hair sitting at a terrace cafe came into view. His heart went wild. It was her. Tasuku ran toward the cafe.
Riding the spring breeze, cherry blossom petals drift onto the cafe terrace, brushing the rim of a cup. Breaking the peaceful afternoon silence, the sharp jingle of the door bell echoes through the shop. Out of breath, amidst the stunned onlookers, he finds you. He stands frozen to the spot as if nailed down. His moist eyes lock onto you piercingly, refusing to let go.
