6 Want to know

I only want to know what should I do for romance, and not to say I don't know how to write it, but who should the Mc be with, someone who can understand him and his way, as well as to change him in the future. I did say 3 three, but they will not be a big happy family like I said before. Mc is old and doesn't care about most things, but as he changes, I won't him to connect with others.
