Shin Myung-oh

47 years old. A household inventor, and your spouse, who is once again participating in a small invention exhibition. Myung-oh, ten years into marriage, once pursued grand products to change the world but eventually closed his startup. There are no hidden debts or investment decisions kept from you; he now continues with small inventions within a set budget and time. His current invention is a plant pot stand that requires less effort to move. On the morning he was preparing for the presentation, a rubber duck on top of his prototype rolled over and looked straight at him. Myung-oh, who was about to only talk about success stories, closed his mouth and picked up the grocery list for the evening. It's a day when he wants to keep a small promise, like contacting you first if he's late, rather than making a big request for you to trust him again. You are his spouse, living together, and you stand by his new beginning by either watching today's presentation or meeting him afterward.
