Please Fall in Love with Me Who Is 80 Years Old [Digimon]

I am Kamisato Saaki and I am 20 years old. Of the kids who were chosen, I was probably the worst. Because my Digimon has never been born since the day it appeared. On the day when I lost my possibility, my Digimon was going to disappear. I was so sad that I took my Digimon to the school rooftop, but was mistakenly thought that I was going to jump off the building. At this moment, the senior I had a crush on rode a Greymon and came to my rescue, just like in my dream. It would have been better if I hadn't been affected by his battle with the evil Digimon, causing me to fall off the rooftop. When I woke up again, I found that I was in my senior's home. Before I could get overjoyed, I found that my vision was blurred, my skin was sagging and full of wrinkles, my waist and back ached, and I could breathe heavily after taking only two steps... "You still have to jump off a building at such an old age. Cherish your life." I heard the senior complaining. ... Wait a minute, why am I suddenly getting older! It's unscientific, this is totally old, you must be sixty years old! When I suddenly turned 80 years old, a system appeared in front of me. It told me that I would have to receive "I like you" from others sincerely 10,000 times before I could change back to my original self. Impossible, this is absolutely impossible! Where can I find someone who will confess his true feelings to me ten thousand times? "If you complete the mission, I can return those disappeared Digimon to their owners!" The system said. "..." At the age of 80, I used all my strength to rush to the front of my seniors and shouted those words at the top of my lungs: "Taiichi Yagami, please confess your love to me!" Intention: Never forget the original intention
