help finding a romance manga please

[Tidus45]

I will give a bit of info me and a friend remember about it.

she's supposed to marry a dude who was born at the same time on the same day as her and growing up she keeps seeing pictures of him so she's like totally convinced he's her destined soulmate, but when they meet she gets confronted with reality that he was forced there and he had no idea who she was. And she helps him escape, but he does fall for her because she's very kind
