Kouguu no Omega
This had me worried for a long minute. Ilya and Khalid marry/meet when Khalid is still a child. However, it's made clear early in the story that the legal age of consent is 18 and a time jump does occur. So it's not shotacon, nor does it sexualize their relationship in early chapters. Whew, as I was sayin', I was ready to drop this and run away at even a HINT. The story itself is surprisingly tasteful and does its best to show the political and familial turmoil beyond the MCs relationship. I'm interested to see how it ends.
