As you can see in the recent chapter there were two women getting married. From this we can say that Shin and Wolfgang can infact marry. As for the continuing the bloodline there is no need as he has other relatives who can take his place in the future they do not have to be his child. But there is always (as you said ) an option of adoption.
I won't say I am 100% correct but neither are you.
Thank you for reading.
Some of us are not facing the truth I see and the truth hurts Wolfgang has to continue the royal bloodline by having a child this isn’t a OMEGAVERSE lmao shin cannot have kids he’s a male unless they adopt. It’s ether adopt or he just Marries woman. We probably won’t get what we want. They deserve to be together tho. But there is a high chance we saw to women do it but it’s really all up to the author I feel like we are getting played and they’ll end up being together
