Days of Dating Saiki (Crossover)

The Little Prince's monologue: I'm both unlucky and lucky. Unlucky because, as a child, I climbed onto the roof to make a wish on a shooting star, but the star fell and nearly crushed me to death; when I grew up, I was enjoying the breeze on my balcony when the house suddenly collapsed and almost crushed me to death; one second the sky was clear and sunny, and the next it was filled with thunder and lightning. The tsunami it stirred up nearly drowned me, too. Lucky because, whenever I'm in danger, a pink-haired guy comes to save me. I like him so much. He's so good to me. Saiki's monologue: I'm a psychic, and I have a disastrous entanglement with someone called the Little Prince. The meteorite I blew up when we were kids nearly crushed him to death; the first time we met as adults, I accidentally demolished his house and nearly crushed him to death; when I finally resolved to end this disastrous entanglement, the tsunami I accidentally caused nearly drowned him yet again... Even though I always make it in time to save him, and he's so moved that he wants to give himself to me, I still feel a little guilty. Now we're together, and it seems like he's noticed something is off. Should I come clean? Waiting for answers online, but it's not urgent. *Reader's Guide* The story is told in third person.
