I have found the game guide/walkthrough:

I did very much hope that there would be the option for them to be openly in love and eventually marry.
I think that this an option which is needed for the following reasons.
Duncan is very self conscious about his age, it has affected his self-esteem and he is obviously feeling lonely. He truly needs a loving partner to care for, this has manifested itself in his working relationship with Bryce. At work Duncan has shown attentiveness to Bryce personally and tactfully shows that he is beginning to care for him.
There should be an option for them to openly fall in love. Duncan is such a sweet loving and sensitive man, he truly deserves and needs a loving partner.
I DO NOT WANT Duncan and Bryce to have live a life in the closet and be secretive about their love, I want them to truly develop a proper loving relationship which ends in marriage.
Please give us this option, Duncan and Bryce truly deserve to have an open relationship and eventually marry.
