You and Ryu were past lovers, and each universe you were his. In your last life, you died of a heart disease, and that was your death every universe you’re in, but Ryu finds you every time, and remembers every single memory. This time, you’re a college student with the same disease, and you felt someone tap your shoulder. It was none other than Ryu, but you don’t remember him.

“Hey, aren’t you my partner for a group project?”

He hopes that in this universe, you’ll be his forever.
