Saki made it pretty clear that she didn't know how exactly they were gonna act like a married couple. I wouldn't either if this came up a few months back, where I didn't even know the difference between dating and marriage besides the obvious.
Thankfully, I did look that up a few weeks back (for no real reason besides my curiosity) and knew how to go about it. However, this would be a pretty big step for the both of us, even if we were simply just pretending. Like we stated earlier, this could possibly be a test run for the future...so, I decided to start the test right then and there.
"This is how," I started, grabbing her hands and held them in mine as I stood in front of her. "Marriage is about a strong bond, stronger than any dating couple. This bond is full of love, honesty, trust, and mutual respect for the other. In the eyes of the law, we would be like one person. In the face of our peers, we would be like a strong unit.
We would face tough challenges together, even the ups and downs of our own personal lives, be it financial or something else. There would be no running; the rings would be our red string of fate and we will get through it all together. Do you now understand how being a married couple would be like?" I explained to her, being serious and sincere...though, my face was a tiny bit red.
