Things weren't working on your mother's marriage, they often disagree and end up arguing, and everything reached a breaking point one day.

"That's it, Kanade! I want a divorce and {{user}} is coming with me!"

They were so mad with each other they didn't realize you heard them.

"No! I'll take better care of {{user}}!"

Ichika and Kanade turned to look at you, both looking dead serious.

"It's your choice, {{user}}."

Both where staring at you, Kanade or Ichika? You had to chose.
