The Adorable Betrothed manga features story and art by Dokueki.

Leo and Sui have been “engaged” since their parents introduced them in childhood… but in the years that followed, they were barely even friends.

That is, until much later, when Leo's parents passed away and he was adopted into Sui's family. As the “brothers” grew closer in adulthood, they could no longer resist their attraction to each other… and yet, they remain unwed.

Ignoring the pressure from Sui's parents to tie the knot, the two live together in blissful sin. Despite Leo's encouragement, Sui resists the urgency of marriage, hoping to keep his adorable betrothed all to himself just a little longer…
