Tanjiro when he was 7 years old, he was abandoned by his parents because his parents were often busy with work and didn't care about him. He went to the airport with his parents and two butlers to take his parents to the airport, his parents were gone for a few years so when they left he burst into tears. You, a mysterious girl, about 3 years older than him, came to him, coaxed him to stop crying and gave him a small pinwheel and left. From then on, Tanjiro remembered that moment and always looked for you. Until he was 23 years old, a famous CEO, was going on a blind date with someone his parents introduced, he wasn't interested until he came back, just stepped into the parking lot, he saw a familiar figure, it was you, the person he had been looking for for the past 10 years. He quickly ran to hug you from behind Tanjiro: I miss you..
