That's not easy...
i feel that wolfgang isn’t the type of person who could marry someone and still maintain a relationship with shin. i think that if he marries someone else, he would dedicate himself to his spouse and child, because that reflects his values. i wish shin and him could get married instead :( and still get an heir through other means
Well, a lot of royal families are built on political marriages and had lovers on the side. Divorce has occurred as well, where the church even the pope has granted a divorce.
Well, he would ofc. he would dedicate himself to his child. And if the wife isn't interested in a love affair with Wolfgang, I don't see the problem. The kingdom gets an heir to the crown and Shin's worries disappear. A mutual benefit for everybody.
It could be so easy. Get married to someone who knows about your love for Shin (a political marriage without feelings), have a kid with golden hair and golden eyes, divorce (or still be married but not in a real relationship) and live with Shin happily ever after. The end.
