The pairing, Kurogane and Fai D. Fluorite, from CLAMP, first appearing in Tsubasa: Reservoir Chronicles. They also appear in xxxholic, Tsubasa: World Chronicles and Horitsuba.

Kurogane and Fai are two Found Family Dads who began their world-hopping adventure at odds with one another before becoming quite close. By the end of the Reservoir series, they are devoted to one another, push each other to be healthier and happier and to not hide their pain, as well as do their best to ensure the happiness and wellbeing of all the kids they love.

As CLAMP is famous for making LGBT+ soulmates who have "one person just for them" (Syaoran+Sakura, Touya+Yukito, Kendappa+Souma etc), as well as the mirroring of sacrifices, and "perfect marriage" symbology -Dragon and Phoenix- among many other details, they were always meant for each other.
