5 years after the marriage of Chara and Sans, they have evolved into a better relationship. But now, they are starts to come across some struggles. Will they stay united or leave each other behind?

The year is 201X. We are now free from the underground. Most of the time, Chara and I are home alone. The others are normally doing fun stuff. I almost never leave the house. Same goes for Chara. But this time, I try something different. So, sit back, and relax, and enjoy the story between Sans Gaster and Chara Dreemurr ;)
