Future Fumi: "It was love at first sight. As Ayano shyly averted her eyes, she was shyer than ever, yet glowing brighter than the snow under the moonlight. The kairo in my pocket kept my hands warm, but she was the one who warmed my heart. And that, kids, is how I met your mother."
Kairo is a Japanese disposable pocket hand warmer
Hahaha, he went oooohhwah. He has no defence against her
Hahaha, her reaction to snow. She's still a kid. So cute
Whatever happens with these 2 in the future, I want both of them to be happy
