After being reincarnated in another world for 25 years... somehow I've become the fiancé of a 5-year-old princess (bewildered)

# Translation Twenty-five years have already passed since my reincarnation into another world... I, Latilio, was born with memories from my previous life, which made me extremely timid about romance. However, as a result of getting way too excited about the fantasy world I longed for... for some reason, I've become engaged to this country's princess. And she's only 5 years old. What on earth should I do about my romance as someone heading straight for lolicon territory? ※ A laid-back, fluffy romantic comedy between an age-gap couple (lolicon welcome). Honestly, I wanted to make the protagonist's age 21... (in terms of the joke) (21)⬅ If you write it together, those who understand will get the joke (not related to the main story)
