No sequel ? Wedding and so forth ?

The "wedding" was probably the party they had at the end. Since Saku and Ryota can't legally marry, Saku's parents adopted Ryota instead so he can be part of their family. Friends and family know that means they're in a relationship, but for publicity's sake, Ryota is the adopted son of the family. At the end, the party was to celebrate Ryota getting adopted, so that's as close to a wedding as you can get I guess lol An unofficial one would have been nice though.

So they wont or would be having kids after they're married? And what about the theory Hans said about male vampires' life span at only 39 years old ? Sorry, i mightve missed that part

If I remember correctly, Tsukasa found out that the theory of devils' lifespan being so short, was based on research that was done in a rather secluded area. Meaning, that this isn't the case for all (male)devils. As for the kids, I think they will have them, be it through addoption or in the same way Yuuki was born. His mom is the researcher of this after all, she'll know what to do for sure ^^
